[BiO BB] discrepancy between probe sets for same gene in microarray

[lichunjiang]

Dear colleagues,
       I’m now dealing
with microarray data and I encounter a problem as following:
Quite sometime multiple probe sets
are adopted for a same gene, while data produced with
these multiple probe sets does not
agree with each other well, sometimes, they are quite 
different even shows a contrary
change trends. I wonder how does this happen and what 
should do to deal with the
problem.
Thanks for your help!
Cheers,
 
Lichun
