[BioC] exporting mas5 data with xps

[Addiel U. de Alba Solis]

Dear Christian,

I am following the script4exon you provide to process HuEx-1_0-st-v2 data.
When exporting after processing and making MAS5 calls:

> export.expr(data.x.mas5,
varlist="fUnitName:fTranscriptID",outfile="MAS5EXPRLEVELS.txt")

The command replies with:

NULL , and then exports the text file

However instead of having a transcript ID field(label) it has a ProbesetID
field. Is this the transcript ID?

Also a general question. Is your transcript ID referring to the
transcript_cluster_id in affymetrix annotation?

Best regards,

Addiel de Alba
