[BioC] gcrma

[Crispin Miller]

Hi,
I've been trying to play with gcrma...
When I chuck an affyBatch object, eset,  at it (containing 25 U133A arrays) as follows:

> normalised <- gcrma(eset)
It gets as far as background correcting and then dies with:

Error in tmp[1, ] : incorrect number of dimensions
and then a few warning messages:

NaNs produced in log(x)

I get the same if I try different normalisation techniques or mle instead of eb...

 I have installled both the hgu133aprobe and the matchprobes libraries...

I was wondering if anyone can help?

Cheers,
Crispin
