[BioC] GCRMA error

[Dion Whitehead]

Hi,

I have an unidentied error in the gcrma package.  I'm stuck on the cause:

 > gcrma.cold.control <- gcrma(raw.cold.control)
Computing affinities.Done.
Adjusting for optical 
effect........................................................Done.
Adjusting for non-specific 
binding........................................................Done.
Normalizing
Calculating Expression
Error in sigToEnv(signature, fdef) : Trying to get slot "signature" from 
an object of a basic class ("NULL") with no slots


The raw.cold.control object is:
AffyBatch object
size of arrays=712x712 features (221801 kb)
cdf=ATH1-121501 (22810 affyids)
number of samples=56
number of genes=22810
annotation=ath1121501
notes=Merge from two AffyBatches with notes: 1) Merge from two 
AffyBatches with notes: 1) Merge from two AffyBatches with notes: 1)  , 
and 2)  , and 2)  , and 2)

R version 2.0.1
gcrma versionl 1.1.3

I would really appreciate some feedback on the possible cause of the errors.
