RMAExpress 0.5 alpha 2 has been released. It can be downloaded at


Changes since 0.5 alpha 1
- Improved support for dealing with exon arrays 
- An change in the RME format for CDF files as written using RMAExpress
or RMADataConv (the previous format will still be read fine)
- An export option for outputting expression values in a binary format
which sides steps the need to output to text files which can quickly
become unwieldy. 

- Right now the only purpose of the export function is for getting
RMAExpress computed expression values into R/BioC. Specifically as of
version 1.7.6 the affyPLM package includes a function ReadRMAExpress()
which will read this output file into an exprSet or R matrix. 
- Complete details on the internals of this file format will be soon be
available for those that want to write their own parsers for their own
purposes (of course you can read the code also if you wish).
- This is currently only in the GUI app. It will become an option for
the console application in the next alpha version.
