[BioC] Unable to perform GCRMA/RMA with cdf file 'mogene11stv1mmentrezgcdf'

[Trent Simmons]

Hi Jim,

That has solved the RMA issue.  Thank you very much!  Any idea for the GCRMA issue?

Best,

Trent

The default for gcrma() is to use the MM probes to estimate GC-specific
background estimates. However, the Gene ST chips are PM-only chips.
However, there is an argument to gcrma (NCprobe) that you can use to
point to the negative control probes.

RMA didn't work either, but in this case, it seems to be that the RMA script is looking for a CDF file called 'mogene11stv1cdf' instead.  Once again, anyone else with this issue or suggestions for a fix?

See the cdfname argument to ReadAffy.

Best,

Jim
