We're planning to combine FPKMs of several GEO datasets for our project. However, these projects uses different gene annotations on GRCh37--some use hg37 and some use hg19--for their gene counting.
Do you think, in such a case, that it is necessary do "rebase" the FPKMs using gene lengths from the same annotation?
