there are more '-1's than '0's, again showing there is a skew to negative
ratios.
Am I missing any preprocessing that is required besides the doCRMAv2?
Thank you for your help,

Hi,
This seems to be working well, although I'm concerned with the raw counts

Dear all,
I'm processing a set of ~200 SNP6 .cel files and then performing
segmentation with CBS. But I would like to know how to extract the data
points data-frame that is used as input to DNAcopy CBS.
The code is as below:
# install.packages('aroma.affymetrix',
Hi all,
I'm processing a large set of SNP6 samples (1020) and performing CBS
segmentations afterwards. It's a very lengthy process and the annoying part
is that it systematically crashes on the last sample, see code and output
below:
# Run CBS paired segmentation with pooled normal samples
ing without re-calling the fit function from CbsModel?
Thanks a lot,

e an alternative way to export the regions without running the
CbsModel again? I have the previous script running (where only the last
sample was ran in CbsModel) and it seems to be exporting all the processed
samples.
Thanks a bunch,
