Hi,
This is my first time analyzing Illumina microarray data, so I'm not
familiar with the data format as exported by BeadStudio or
GenomeStudio. The problem is that I can't get read.ilmn to read in
either the sample data or the control data. The error I get when
reading in the sample data alone is as follows:
Error in `rownames<-`(`*tmp*`, value = list(PROBE_ID =
c("ILMN_2896528", :
length of 'dimnames' [1] not equal to array extent
When reading in the control data I get the following error:
Error in readGenericHeader(fname, columns = expr) :
Specified column headings not found in file
This data comes from the Genome Technology Access Center at WashU and
they claim the data is directly exported from GenomeStudio.
Could it be from unexpected characters in the file (e.g. R doesn't
like #, -, and other characters in certain situations)? There aren't
any #'s in the file, but I'm curious is read.ilmn handles these cases.
The sample names do have '-' in the name, but I tried removing those
and it didn't make a difference.
I appreciate your help!
Mark
