[BioC] A circular problem: re-annotation of custom PM only probes

Hi Ariel,

Well something seems to be amiss, because the latest version of 
Bioconductor does not have a matchprobes package and hasn't for some 
time.  Can you please provide the output of sessionInfo()?  I am 
concerned that you might possibly have packages mixed from different 
releases.  It is still not clear to me what what is happening to you.  
Do you have a reproducible example of what you did so that I can try it 

And while I am mentioning these things it might help you to have a peek 
at our posting guide:
