Greetings Fellow Cytometrists:

I am working with Dr. Dorothy Lewis who chairs the
ISAC Data Presentation Standards Committee whose aim
is to derive a consensus concerning the presentation of
flow cytometry data in the literature.  As a result, I have a
request I'd like to make from each of you.

Through the years, many of us have seen published flow
cytometry data that was presented badly, or just outright
wrong.  These errors could be due, in part, to improper
machine "set-up", minimal event collection, or just plain
sloppy presentation. We are interested in reviewing any
published paper in which you feel errors of any kind reside
in the presentation of flow cytometric data.  We are
looking for any papers you feel would make appropriate
(bad) examples.

We would be interested in any examples that you have, or find.  As a
guideline to what we are looking for:

1) Data Interpretation:  - Examples where statistics are inappropriately or
incorrectly used with either single or two parameter histograms. 
- Examples where conclusions are drawn with "quantitative" data but are
presented without statistical analysis.
- Inappropriate, or lack of use markers or regions.

2) Examples where instrument set-up using compensation was not described or
incorrectly used after data was obtained.

3)  Any example where the conclusion in  a paper is in doubt due to
improper use of flow cytometry.

4) ANYTHING that you feel is a substandard use, presentation of, or mis-use
of flow cytometry.

What we'd like to ask is that you send any examples to us 
at the address below.   We would like to obtain as many
examples as possible from any and all aspects of flow
cytometry - basic science, clinical science, one parameter,
two parameter, DNA analysis, or anything. 

Additionally, I would encourage you to feel free to email
the reference to me as well.  Feel free to state what you
think is wrong with the examples you are submitting.

We would like to state for the record that ALL submitted
examples WILL be kept CONFIDENTIAL with regard to
who sent them. 

If there are any questions or concerns, please feel free to
phone or email me, or Dr. Lewis who is Chair of the ISAC
Data Presentation Standards Committee 
(dlewis@bcm.tmc.edu).

Many thanks and we look forward to receiving your
submissions.

David
