Hi, I have data (txt & idat) of custom iSelect HD custom array and have the bpm(bead pool manifest) file and a csv file and would be intrested in normalizing analyzing. I have 5105 snp on the array but only 148 are of intrest and there's no way to subselect the 148 prior normalization in GenomeStudio. So i would like to do that in R, load the data, subselect snp of intrest normalize and plot snp clusters. I take a look at the available packages that handle that (beadarraySNP and crlmm). crlmm work with infinium 2 but not for the custom array. Any one have the chance to hande custom iSelect array before or would know how to do to analyse custom array in bioconductor ? Thanks in advance for help and suggestion.
