[BioC] Vsn and rma with PM only arrays

[Roumyana Yordanova]

I am trying to use rma or vsn on PM arrays (in particular Mouse 430).
Both stoped with an "error in .local(object,...) : subscript out of 
bounds".
(mmindex returns 0 for all probes. Is this the right coding for PM 
arrays or this is the problem?).
Thanks for any help.
