Dear Henrik,
I am trying to run GcRMaBackgroundCorrection on HTA2.0 arrays. I built my
own probeflat file, that I think that it is correct (but I may be wrong).
After running this code I get the error
> bcgc <- GcRmaBackgroundCorrection(cs, tag=c("*","r11"),type="affinities");
> csBCgc <- process(bcgc,verbose=verbose,ram=40,safe =F);

So it seems that there are "probe x position out of range [0,2572]"... My
surprise came when I found that, indeed there are!!!!
I checked (downloading the unsupported HTA-2_0-r1-exon_cdf.zip file from
Affymetrix) after changing periods to commas that running
cdfGFile <- file.path(Path, "HTA-2_0,r1,exon.cdf")
system.time(df <- readCdfDataFrame(cdfGFile)) # Takes more than 30 minutes
in my laptop...
the df data.frame contains df$x out of the range 0:2572. In other words, it
seems that the dimensions of the array are somehow switched and the sanity
check of function getProbeSequenceData.AffymetrixCdfFile throws an error.
In other words, in the official (albeit unsupported) cdf from Affy, there
are probes with x position larger than 2572 and the dimensions seems to be
switched. I was wondering if there is some type of bug: Affy arrays used to
be square and therefore, the range for x and y was identical.
Is there any way to circumvent this sanity check since everything seems to
be working properly.
Best regards,
Angel
