________________________________________

Only two more weeks until ISAC, that biennial bacchanalia of flower power

and fun!  So I hope you'll excuse a bunch of blatantly commercial

announcements to the list, but endulge me this one time and read on.

 

At the show we'll be releasing FlowJo Version 4.  We've got new platforms

for overlaying and clustering, we've made it work better across the

Internet, added all sorts of new conveniences, and spiffed it up with the

new OS X look and feel.  What was already the best analysis software in flow

cytometry has gotten a whole lot better.

 

At the meeting, Tree Star is proud to be sponsoring the CyberCafe, your link

to home and responsibility while you're in carefree San Diego.  Check your

email, surf the web, download the slides you'll be presenting at ten.   A

cadre of California companies has contributed to bring in a premier local

roaster to satisfy all your latte urges.  We hope you’ll all drop by and see

what we mean when we say we're committed to Java.   The network is going

wireless this year.  Just pop a 802.11 card in your laptop, and while your

neighbor plays solitaire through the keynote, you can be reading e-mail.

 

We're going to open the CyberCafe with the Second Biennial FlowJo Users

Group Meeting,. Saturday night May 4 at 8PM.   The first user group meeting

was cancelled for lack of interest when Dave Novo brought in a case and a

half of French wine, so this year we're going to try real hard to assemble

to the point where we can see the show of hands on something before we

disband in search of alcohol.  We'll have a whole bunch of Macs running

FlowJo v4 under OS X, and you can bring your own data and get into big

arguments about compensation.   Be the first to get the newest FlowJo

t-shirt.

 

All you Windows fans out there, come by our booth to see FlowJo running on a

PC!  We’ll be previewing the long awaited Java version of FlowJo.  We’re

still not ready to release it, but we’ll be giving a peak as to what it is

going to do.

 

For those who haven't found it yet, we've unveiled a spanking new FlowJo

website. Flowjo.com is chuck full of new content, functionality and spunk.

Automated price quotes, online ordering, a FAQ that will guide you to new

depths of understanding, and none of that awful yellow on black text.  The

search engine even works.  No ads & cookie-free.  Check it out.

 

Specifically, you should check our pricing. Prices are going up on May 10.

It has been a number of years since we've changed our prices and with the

development of the OSX and PC versions,  it¹s time for a leap.  I guess

there's no such thing as a free launch.  Anyway, this may be a great time to

buy that FlowJo ten pack you've been thinking about.  Licenses purchased

before May 10 are entitled to a year of free upgrades, including the 4.0

release.

 

Unleash the flower power!

Paul,

 

Thanks for the kind words, but I can't take all the credit for the

CyberCafe.

 

Apple generously provided all the Macs.  IT departments around the world may

say that Macs are hard to network, but we put a dozen Macs on the Internet

in under an hour.   Apple sent top of the line G4s with Cinema displays, and

Titanium PowerBooks, as well as a bunch of iMacs.  Imagine what the lines

would have been like if we only had three computers, as we did in

Montpelier.

 

The true highlight of the cafe was the free espresso. Thanks to Phoenix Flow

Systems, Guava Technologies, PROzyme and Becton Dickinson for contributing

to the coffee fund. By the time we got to the coffee I had blown the

marketing budget on this endeavor, and these companies stepped in to make

sure you had Ryan Brothers coffee instead of the swill we'd have gotten from

the hotel.  I also extend a special thanks to Kevin Becker for bringing the

Mar Dels to the banquet.  The best band of any ISAC I've attended.

 

The CyberCafe crew was Jennifer Wilshire, Maciej Simm, Adam Treat and Amy

Hsu. They thought they were getting a leisurely week on the beach, and ended

up working 9 to 9 every day to keep the CyberCafe running.  It was an

exhausting schedule, and they were tireless in their support of the

attendees' Internet needs.  It never would have come off without them.

 

Sophia Ascani and Alexandra Treister tie-dyed the 350 shirts.  Each one is a

unique work of art, and each was hand-dipped.  Our garage floor has the

stains to prove it.  So wear them proud, and wash them in cold water.

 

We've agreed to do it again at ISAC XXII in Montpelier. 

 

I'm just thankful

 

this congress is only held every second year. 

 

All this marketing crap

 

Just gets in the way of my programming.

 

Au revoir,

 

Adam

The important extension is that the probability binning methods include

multivariate

comparisons.

 

Your points are valid improvements over the well known limitations of the KS

algorithm, but they still look at only one dimension of the data.  This was

exactly how we started when we set out to add comparison statistics to

FlowJo.  But when we realized we should look at all of the data, and

implemented the multivariate comparisons, things worked much better.

Suddenly the software started quantifying the differences in ways that more

closely matched human assessments, and it also became able to gate on the

events that constitute the important differences.

Hi Marty,

 

Just to reassure you, FCS Express does use the linear model correctly. It may shock you

to learn that other people, aside from your friends at Treestar, can read Dr. Bagwell's

paper and actually understand it enough to implement the algorithms that he describes.

 

FCS Express allows you to enter the files with the single stained controls and it

calculates the matrix values based upon the data in the file. In addition, in order to

see how slight changes in the compensation can distort your data, you can change the

compensation values with sliders to see what happens. Its a great for teaching people

the difference between proper, over- and under- compensated data. You can also enter

a user defined value to smooth out the digitization errors that can occur in the low

end of lower resolution data.

 

If anyone finds any problems with the compensation (which hasn't happened yet), please

let me know and of course I will fix any errors. But until that happens, I think that

your assumption that FCS Express uses the linear model correctly is actually a very

good one.

 

-Dave

Advertising

________________________________________

I agree that there have been far too many commercial-oriented emails

on the list.  I appreciate the efforts of most manufacturers to

withhold from advertising on this list (plus, of course, the efforts

of Steve & Paul to filter those out).

 

The list, which is an outstanding forum for exchange of information,

has been occasionally used to identify substantially new products

which can significantly impact on how we do experiments.  I feel that

the Molecular Probes email of 10/30 clearly does not fall into this

category; the new product advertised was no more than a slight

modification of the existing one.  Such an email should be directed

solely to the person requesting information; if that person then

collates responses and puts it back on the list then so be it.  But

for manufacturers to directly respond in this way is

counter-productive to the goals of this list.

 

I would like to propose a 6-month moratorium on all emails that are

no more than advertisements.  Note that I write "would like

to"--because I'm not sure that this is possible.  I don't want to put

any additional onus on Steve or Paul to filter out the borderline

emails.  While these may be easy to identify when they come from

manufacturers, it could just as well be considered blatant

advertising when they come from a user.

 

Therefore, perhaps we can see if the commercial participants on this

list could exercise self-restraint rather than requesting a formal

censorship of advertising emails.

 

Thus, if you are a manufacturer, and you are responding to somebody's

request for information, do so privately to that person ONLY.  It is

up to the person requesting information to decide whether or not the

information received in response to the query warrants a summary on

the list.

 

If you are not a manufacturer, and are responding to somebody's

request for specific information, please consider whether your

response (that identifies a specific product or manufacturer) is of

general enough interest to warrant the list.  If it does not, then

simply send it privately to the person who requested information, and

let them decide whether to post the summary of responses.

 

In general, I urge people to err on the side of caution and send

their information only to the person who requested it.  Realize that

if several people want the same information, they can always request

it from the original poster!  I have posted queries to the list;

people have sent me emails asking me to forward to them the

responses, which I did.

 

This process can significantly cut down on emails that might be

viewed as too commercial.

 

mr

Well, I disagree. There aren't that many commerical e-mails, and for us, an isolated

startup company, separated from academic institutions, one of the commerical e-mails

was helpful, we would not have know about the product otherwise (see I am even not

going to advertise it!).

 

All best,

I would not like for Dick Haugland to feel that we are criticizing his participation in

this list.  Molecular Probes has been a HUGE help to all flow and imaging cytometrists.

Advice from that company has been good, generous, dependable,  and without strings.

The new MP handbook is a fantastic source of information.  I would hope that advice

from Dick will continue to be submitted to the whole network --- and if he gets a bit

of free advertising from it,  then he deserves it.

I need to add that I was NOT suggesting that this network give any special dispensation

to Dick Haugland and Molecular Probes.  They,  like many other companies, are of

great benefit to the flow community.  I was suggesting that we be a bit relaxed in

our willingness to accept subtle advertising in general  --- because we can benefit

from being able to get advice directly from people who are at the forefront of flow

development.  Obviously,  knowing where to draw the line can be difficult.....

EMAIL ABUSE - how to stop

Colleagues: I am sending out a copy of a message I have just sent to

RNWAY laboratories of South Korea and all 20 worldwide distributors of

RNWAY products most of whom are highly reputable companies. I am only

sending it to you because I am going to propose to create a small

"SCIENTISTS against EMAIL ABUSE"  type of revolutionary action.........

 

I won't send you more copies of what I am going to send out, but I will post

them in a prominent place on our website so that you can follow and

participate in the action.

 

I am truly sick and tired of receiving literally dozens of unsolicited crap

messages each day. However, receiving them from supposedly reputable

companies drives me really crazy. These, I can do something about and I am.

The rest are virtually beyoned any reasonable solution. As you can see, I have

started with RNWAY, a company that I have requested a dozen times to

remove me from their abusive lists. This week they sent me an attachment to

boot....- something they do constantly. This made me really mad.

 

Perhaps it was the beef I ate in the UK this week, but I got really mad when

RNWAY filled my box yet again.....and I am going to set up a place where

people can register copies of messages they send recording their requests

for removal. This record will become a documentation place you can copy

your messages to for any future legal actions.  We will code the email

address of the requestor so you don't get further abuse, but we will publish

the list of companies that continue to abuse us.

 

If you have suggestions, please let me know.

 

Sincerely

 

"Mad Cow" Paul Robinson

Purdue University

---------------------------------------------------------------------------

 

Here is the email that I sent to RNWAYs 20 worldwide distributors

---------------------------------------------------------------------------------------------

You are receiving this message if you are associated with RNWAY products.

 

We have continually requested removal from RNWAYS abusive and constant

emails. It is against Federal law in the United States to continue to send

unsolicited emails after requests to discontinue are made. RNWAY posts a

privacy policy that they make no attempt to enforce.  Our requests have been

documented by the university on numerous occasions. RNWAY is now liable

in the United States for severe penalties under US law. As a distributor of this

company you may also incur loss of trade, or reputation for the actions we are

going to take.

 

As scientists who buy your products, we are going to exert our own economic

power. We will be letting members of our various associated networks that

RNWAY will be listed as an EMAIL SPAM ABUSER. We will be

recommending that all of our users do not purchase any of their products if

they continue to abuse our email accounts.

 

As a scientist who uses the INTERNET as a crucial component of my

communication with others, I am sick of abuse of my email and I have

decided that I am going to do something about it, one company at a time.

 

This message has been copied to the 20 companies that distribute RNWAY

products around the world. This is the first of a series of actions. It will also be

copied to 3000 scientists who may have an interest in stopping this type of

abuse.  It will also be posted ona  public site that had last year over 5 million

access. If you as a distributor want to make a profit on selling (scientists)

products, I suggest you ensure that the comanies you deal with don't abuse

us. If they do, we won't buy their products and you will lose money. Do you

hear us?

 

Yours sincerely

Paul,

 

Sounds like you're advocating fighting disease by eradicating the

antigen instead of boosting the immune response.  You can organize all

you want on eliminating the pest, but until they put a stamp tax on

email, a better approach is to let the

messages be out there, but have them filtered to oblivion before you

ever see them.

 

In your case, the postmaster at Purdue is probably already filtering

millions of messages a day that come to the thousands of email users on

campus. They are probably capable of shutting down any RNWAY mail, and

spreading the word to other postmasters that they also should filter

those messages.

 

So if you can get the IT people at the university to tighten their

sieve, that's best. Otherwise you have to switch to an email program

that has good junk filters.  I think I get 500+ messages a day, and

only 10 to 20 make it past the junk filter.

Until last summer I was using Outlook Express and spam was a huge

problem. Since then I switched to the free Mail program in OS X, which

just added special features for spam detection and removal.  Its

probably 97% effective, and I haven't found any false positives.

So, of course, the best answer is to get a Mac  :)

 

I'm sure the PC mail clients are addressing this issue as well.  I

believe there are central databases of offenders so programs can learn

from others which messages to delete.   I would imagine this is the

most important feature in any email program sold these days, so I bet

Eudora or other third party mail programs have this solved.

 

There's a lot of information on the subject at:

 

http://spam.abuse.net/

 

Whether you fight the problem on the server or the client, it

definitely is worth getting it cleaned up.   I found it screwed up my

whole communications process because every time I wanted check email, I

had to wade through dozens or hundreds of useless ads.

 

Adam

FlowJo in an offline analysis package that will read both EXPO (PC) and

CellQuest (Mac) files.   You can compute the percentages in each of the

phases (as well as under-G1 and over-G2) for any gated population.

 

We currently have a limitation in the ability to export all of the cell

cycle statistics for all of the samples to a spreadsheet in a single step,

but that is implemented in the next release.

 

More info at:

http://www.treestar.com/flowjo/html/cellcycle.html

 

I get a lot of requests for the references to the models, so let me give

them here:

I'm working on an FCS file editor, one function of which will be

an automated date changing function.  So if there are Y2K problems

you can set back the date on the cytometer, and then change all

the files in one shot after collection. 

 

This will be a free utility, and will do other keyword editing too,

but a big motivation is just to provide a quick and dirty solution

to the Y2K issues that will affect many of the cytometers out there.

 

The design spec is to just add a user-specified number of years

to the $DATE keyword, and to write it back to the file (using

4 digits for the year).  The original date field will be put in a

different keyword, and the program will also be able to restore the

file to its original state. If anyone has more elaborate requirements

than that, I'd appreciate it if you'd drop me a note.

If I may clarify...

 

Judging from the phone calls I'm getting, Cariappa may

have implied that FlowJo is a cross-platform package.

I think he meant that FlowJo reads data collected on any

cytometer, whether it was hooked to HP, PC or Mac.  FlowJo

itself still runs only on the Mac. 

 

This may be unclear, because we are running a Summer

$99 promotion, in conjunction with DeNovo Software

 

.  They sell the PC based analysis package: FCS Express. So, the

solution I can offer you for Windows is at:

   <http://www.denovosoftware.com/>

 

The promotion is a good deal on either platform.

 

We are working on Win-FlowJo, but it's not close to ready.

The bad news: there is no announced release planned for

a Windows product in the foreseeable future. 

The good news:  more for the Mac is coming pretty soon.

FlowJo uses a hierarchical rather than a logical gate structure, ie

you don't work by creating two gates and then combining them, rather

you place the first gate, open the gated plot and place the second

gate directly on that plot.

 

The best way to get into FlowJo is to do the tutorial that can be

downloaded from the web-site (<http://www.flowjo.com/tutorial.html>).

Until you have got your head around the fundamental differences

between the programs it is very hard to compare them.

sent to the list myst be intentioned to the list. Otherwise
individuals communicate directly. We will not be changing this
method as it is the one favored overwhelmingly by the group. There
are virtually no trash emails on this group. There is a very good
reason for that. If anyone sends trash mail, they are rapidl;y
deleted from the list and their access is barred. This makes a very
strong incentive to keep a high quality of discussion. My experience
with listserves is the rubbish is overwhelming! We have considered
many times the advantages of a listserve , and the disadvantages far
outweigh them. Since we are one of the older scientific discussion
groups out there, our track-record speaks for itself. We do encourage
people to tabulate results of their questions. They invariably do
this and we thank you.

While, I appreciate this might generate some email, let's not fill
the box. We are NOT going to change it anyway!!!

RE: commercial announcements

From: Dr. Robert Ashcroft (cytomat@netcore.com.au)
Date: Tue Jan 05 1999 - 02:04:46 EST

Dear Bill,

As an academic with commercial connections, I have found that it works if

you do either of two things:

Invite the interested parties to request you reply with a file attached to

their responding email, or simply send an attached file in the original

mailout.

 

Most people favour the first, as there are lots of people who resent the

attachment file in the primary mailouts.

 

In the second case, from the marketing viewpoint... the problem is adding

enough detail (without over-sell) in the List message to motivate the

target persons to request the file, yet not enough to alienate the set of

people who are anti-commercial

 

Hope this helps

Personally, I usually don't mind the commercial comments, but there have

been a few that seem to have crossed the line.

 

 

I would suggest requiring a response in which a company directs readers

to products from their company as a solution to a specific cytometry

related problem to include (parenthetically) a warning such as

"propaganda" or "commercial" or "advertisement" with the subject line of

their response. For example; <bold>Subject: re CD34 staining

(commercial).

 

 

</bold>For a message from a company which is not a response for help, but

more directly an advertisement, the subject line of the email would also

include "propaganda," or "commercial" or "advertisement."  In this case,

most of us could happily delete the message before reading it!

 

 

Maybe it's just me, but I like the paradox of a salesperson typing

"propaganda" as the subject of a listserver posting.

Re: Ratio calculation

From: Tree Star (treestar@professionals.com)
Date: Wed Jan 13 1999 - 19:11:06 EST

I haven't done it, but you should be able to fake a compensation matrix that will add FL1 + FL2, then derive a ratio using that new one.    We considered and dismissed the generalized parameter calculator from FlowJo because no one had (previously) expressed the need.  If your colleague can explain why that helps, and it makes sense for others, then we'll support it.   There is a problem that FCS files don't have negative numbers in them, so a general algebraic parser wont work.   Adam   On Wed, 13 Jan 1999, Joseph Webster wrote:   > > Hi All, > A slightly curly request.... :~? > > A colleague wants the ratio of (FL2 / (FL1 + FL2)) from many flow readings. > (He explained why, but I didn't understand...) > > He wants this from many datafiles, so batch processing probably.... > He wants to export this into some other program such as Excel..... > > Several computer packages can produce simple ratios of one parameter > over another, but someone is always wanting more... > > Any ideas? > > Another challenge for Ray Hicks, Adam Treister, Joe Trotter Et Al ;~) > How about the ability to enter a user-defined function or formula to be > applied to the data? > > (The "massaging" possibilities are amazing!-) > >       Thanks, Joseph. > > -- > Joseph Webster > Flow Cytometry Facility > Centenary Institute >

FlowJo, originally developed here at Stanford, now comes equipped with an

integrated cell cycle platform.  It fits both Watson's "Pragmatic" model as

well as the Dean-Jett model (with the Fox modification).  Using an

interactive interface, you can put constraints on many of the fitting

parameters, allowing you to model most DNA distributions.  However, there

is currently no way to model debris background subtraction (a process which

is controversial), nor can it model cell divisions (using dyes like PKH-26

or the like).  In other words, it's not as sophisticated as ModFit, also

available for the Mac, but suffices for probably 90% of the users out there!

 

FlowJo integrates this platform into the unique drag-and-drop interface

that lets you apply your customized models to entire experiments in a

matter of seconds, create graphical reports in which you include

statistics, keyword information, and so forth.  You can even create

template analyses, so that subsequent experiments can be analyzed just by

loading the data into the workspace.

Mark's message lists valid uses for the capability. Clearly there are limitations, but this is flow, so what else is new?  The software is there only to calculate the numbers; it's up to the biologist to make sense of them.   Adam   ----------------------------------- Adam Treister adam@treestar.com 650-508-9349 http://www.treestar.com -----------------------------------

Re: Cost-benefit ratio of FlowJo [Clarification]

From: Adam Treister (adam@treestar.com)
Date: Wed Aug 04 1999 - 16:28:49 EST

If I may clarify...   Judging from the phone calls I'm getting, Cariappa may have implied that FlowJo is a cross-platform package. I think he meant that FlowJo reads data collected on any cytometer, whether it was hooked to HP, PC or Mac.  FlowJo itself still runs only on the Mac.    This may be unclear, because we are running a Summer $99 promotion, in conjunction with DeNovo Software.  They sell the PC based analysis package: FCS Express.  So, the solution I can offer you for Windows is at:    <http://www.denovosoftware.com/> The promotion is a good deal on either platform.   We are working on Win-FlowJo, but it's not close to ready. The bad news: there is no announced release planned for a Windows product in the foreseeable future.  The good news:  more for the Mac is coming pretty soon.   Adam   ----->>> On  4-Aug-1999, Cariappa Annaiah wrote: >   >   I routinely obtain flow data from both Mac and PC based >   machines and so have some experience using Mac/PC data >   analysis software.

New Mac Analysis Software Launch

From: Ray Hicks (rh208@cus.cam.ac.uk)
Date: Thu Aug 26 1999 - 17:59:38 EST

This is to announce the release of FCSPress, a new program for the analysis of flow cytometric data on the macintosh.   Its particular strengths are high quality graphs, on-the-page editing and annotation, intuitive (to me at least ;-) interface, copy and paste of graphics and text into other programs (at full resolution - not just bitmap or screen dump), and ease of use.   You can download a thirty day fully working demo from   http://www.fcspress.com   or   http://www.angelfire.com/biz2/rayh   (the ink hasn't had a chance to dry on the www.fcspress.com address, and it may not be recognised everywhere on the internet yet).   This release is for powermacs only, a "fat" version for non-powermacs is in the pipeline.   If you have trouble obtaining a demo from the web, you can request a copy from request@FCSPress.com <mailto:request@FCSPress.com>.   Pricing for perpetual licence, no time limit, valid for all versions 1.x:   Type                   Initial                cost           extra copies                        quantity Single                 1              $149 (99 pounds)      $149/£99   "Departmental"         5              $749 (495 pounds)      $99/£60   "Institutional"        20             $2095 (1395 pounds)    $45/£30   For further details see the manual on the web page e-mail sales@FCSPress.com <mailto:Sales@FCSPress.com>.   All orders received before 14 September 1999 receive a 25% discount, as do cheque-with-order payments in sterling drawn on a UK bank for single user licences.   Ray
