Hi,

I was having trouble reading my samplesheet from a recent iScan-run of HumanHT12 chips with beadarray and noticed this is probably due to readSamplesheet not grepping case insensitive for [Header] and [Data], so [HEADER] (which was in the file I received) is not found and results in the error:

Error in if (grep("\$Header\$", data[[1]]) != 1) { :
argument is of length zero
No sample sheet was specified. Trying to read all Illumina files in/storagepoolA/sandbox/microarray-qc/analysis

So please consider adding the ignore.case=TRUE argument to the calls to grep.

Thank you very much,
