Dear all, I want to parse BAR-files from Affymetrix. http://www.affymetrix.com/support/developer/powertools/changelog/gcos- agcc/bar.html Crawling through the internet I often read that affxparser is able to read BAR-files. However, I don't find any evidence for that in the Vignette. Any help would be appriciated. Regards, Philippe

You can, however, write a pretty simple little parser for this format using simple R commands. Open the file in binary mode and use readBin, stepping through the format description. It is not fast, but it works OK. Sean [[alternative HTML version deleted]]
