Hi there,
I am trying to run the second step of quantification (i.e. quantifier) following the mapper module of mirDeep2. In the mapping step everything is fine and I get the collapsed reads to be given to the quantifier module. Then, when trying to run the quantifier module, providing mature, precursor and star sequences, the run ends with an error which apparently lacks any suggestions on where the error is.
Here the error:
Fatal error: Exit code 1 ()
Tool generated the following standard error:getting samples and corresponding read numbers

Any clues on what’s going on here? I see a lot of unmapped sequences but this is somewhat expected from a biological point of view as the miRNA fraction is not usually the most abundant in the tissue I am investigating (zebrafish gonads)
Thanks
