Hi Michelle, I've just added vignette 'Paired parent-specific copy-number segmentation (Paired PSCBS) (low-level API after AS-CRMAv2)': http://aroma-project.org/vignettes/PairedPSCBS-lowlevel See if that helps /Henrik On Fri, Nov 11, 2011 at 1:02 PM, Michelle wrote: > Dear aroma community,

Dear aroma community, We are trying to do paired CBS analysis on some Affy SNP 6.0 data using the R package "PSCBS", but not sure how to extract the total CN and BAF values from the raw array files (.CEL) into the needed format (pasted below). It seems aroma.affymetrix has some relevant functions

Hoon, thanks for the note. Yes, there is a discrepancy in how clever the methods are. Basically the AromaUnitCnBinarySet methods go further in trying to figure out what annotations are needed. FYI, contrary to data set directories, the name of the chip type directory will never have tags, which

Dear Pierre, Thank you very much for your prompt reply. FYI. I processed the Affymetrix SNP 6.0 data as follows: - dataSet <-"AffyTestData" chipType <-"GenomeWideSNP_6" verbose <- Arguments$getVerbose(-8, times

Ok, so you have rather old versions running. Start by updating the XML package, retry and report back: http://cran.r-project.org/web/packages/XML/index.html Also, if it still gives and error, what does the following return: > digest(raw) [1] "ecfee3f93033dbbf4a25fd27195ff0e9" /Henrik On Fri,

Hi wisekh6, Although you don't give the code you used to process this data, from what you report it looks like you initially processed your data set using the "full" chip type. See below. On Fri, Nov 11, 2011 at 7:22 AM, wisekh6 wrote: > Dear all, > > After processing Affymetrix GenomeWide SNP

Hi Henrik, Thanks for your help in tracking the problem. I tested your lines of code and it worked up until the point of the " ftr <- readFooter(ufl); " command, here I paste the results below: > ufl <- AromaUflFile$byChipType("Mapping250K_Sty", tags="na31,HB20101007"); > print(getFileSize(ufl))
