[BioC] Problem with setQCEnvironment

Hi,

Thanks for the reply James.

I tried adding a carriage return to the last line, but unfortunately I'm
still having the same problem with my .qcdef file.  I do just get a
warning message after executing the setQCEnvironment command, but I get
a proper error message when I try and run the QC:

Error in setQCEnvironment(cdfn) : 
  Could not find array definition file ' nugomm1a520177cdf.qcdef '.
Simpleaffy does not know the QC parameters for this array type.
See the package vignette for details about how to specify QC parameters
manually.
In addition: Warning message:
closing unused connection 3 (/users/melissamorine/Microarray Data/CLA
Data/nugomm1a520177cdf.qcdef) 


Hmmm, any other suggestions?

Thanks very much,
Melissa
