You can get a list of the group names in the bpmap file by just looking at bpmapA$GroupName. I'm not sure this will solve your problem but perhaps it will.

Also the Ringo and Starr packages have a function to read bpmap files which you could you to read in and then explore the file... best, noah On May 17, 2010, at 5:33 PM, Larry Singh wrote: > Patrick Schorderet <patrick.schorderet at="" ...=""> writes: > >> >> >> Hello everybody, >> >> I am trying to normalize some ChIP-chip data using rMAT and to do so, >> you have to feed your .bpmap to the program (the file contains >> information relating to the design of the Affymetrix tiling arrays). >> Unfortunately, I get an error saying I am working with doubles instead >> of the wanted integer.

Hi Larry and Patrick, Sorry for the late reply. Indeed, it is most likely the error that Larry reported. I have included a test to make sure that the groupName is valid. It should appear in the devel version, as ?of rMAT 2.5.1.? If things go well, I will push it to the Branch release next week. It's a minor fix. In the meantime please make sure your groupName is valid.?
