When dealing with small anchor fraction, the cufflinks would filter out reads before assembly, with the option of "-A/--small-anchor-fraction".
But does cuffdiff do the same filter process?
For example, in my data, anchor of only 2 bases of a read was mapped to gene A. If the tiny part of the read was counted as a fragment by cuffdiff, the FPKM of gene A could be higher than it's real value.
Have anyone met the same problem and how to deal with it?
