Hello, Could you recommend an exon array normalization package which will play nice with xmapcore? I'm currently using oligo, but my knowledge of R is apparently not good enough to take me from a list of probe set expression values to a list of the expression values for each probe set in each protein coding transcript in the X:Map DB. If anyone could point me toward a tutorial or complete script showing a start to end normalization and annotation using xmapcore and any normalization package, it would be a huge help. Thanks, Brian
