To whom it makes concerned: The released version of the package problem suffered from a rather annoying problem in the method 'computeExprSet'. As a result, the expression values computed have very good chances to be rather incorrect (whatever the method you used). Many thanks to Michael Morley for warning us about strange results compared to MAS5.0 (the bug was found while digging that). I would strongly recommend to re-run expression value computation with the version 1.1.1 of the package (should appear by tomotrrow on the website) if you are currently working with expression data obtained with 1.1. Sorry for the inconvenience. Laurent

Laurent: Can you elaborate a bit more? For example, is computeExprSet an internal function used by express or expresso?

I am afraid it is supposed to be the case... however, it seems that express (that was supposed to have this part of its code based on computeExprSet (*)) do not suffer from it (?!?)... may be we shot ourselves in the foot with CVS... L. (*): I just saw that. For consistency (and try to preserve sanityi by avoiding code duplication) 'express' is very likely make use of 'computeExprSet' in the near future

Also, which released version, 1.0 or 1.1? IE, how far back is did the bug go? -Greg > -----Original Message----- > From: Isaac Neuhaus [mailto:isaac.neuhaus@bms.com] > Sent: Tuesday, December 03, 2002 8:54 AM > To: Laurent Gautier > Cc: bioconductor@stat.math.ethz.ch > Subject: Re: [BioC] important bug fix in the package affy > > > Laurent: > > Can you elaborate a bit more?

The release date was Nov. 18th. The release version 1.0 was not subject to this bug. Truly sorry again about that. And I'd like to thank again people reporting bugs/oddities. L.
