Dear all,

          I was trying to normalize a subset of affy data those transcribe
are either P or M (called pm_filter).  I am able to normalize pm_filter
subset by using RMA method, however MAS5 is not working.

For RMA method, I used the following commend:  est<-rma(affydata,
subset=pm_filter).  Could any help me; how do I do this by using MAS5
method?

Regards,
Anup Som
