RMAExpress will process binary and text format cel files together with no problem if they are really from the same chip type. The same holds true for data read using ReadAffy().

One question that perplexed me is that the size of the data is very different, some are around 12 mega bytes (cel files), some are even more than 30 mega bytes, I thought same type of chip should have similar size of CEL files, why they can be so different? > > > > Many thanks, > > > > James > > > > > > --------------------------------- > > Pinpoint customers who are looking for what you sell. > > [[alternative HTML version deleted]] > > > > _______________________________________________ > > Bioconductor mailing list > > Bioconductor at stat.math.ethz.ch > > https://stat.ethz.ch/mailman/listinfo/bioconductor > > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor > > > > > --------------------------------- > > > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor
