SequenceLength statistics computes the length (in bp) of the sequence of one species. It returns 0 if no sequence for this species is found in the current block.
It will send an error however if the block has more than one sequence for this species (be sure to use the
Subset filter before, if needed).
maf.filter= \ [...], SequenceStatistics( \ statistics=(\ \ [...], SequenceLength( \ species=species1), \ [...]), \ ref_species=species1, \ file=data.statistics.csv), \ [...]
The species for which lengths should be reported.
