- setting read group ID to: ZDI4H940NP2
- setting sample name to: unknown
- setting sequencing technology to: 454
- trimming leading and lagging N's. Mates with >4 interior N's will be deleted.

- parsing FASTA files:
reads: 318,127 (4,773.9 reads/s)

Filtering statistics:
============================================
# reads deleted:               135 (  0.0 %)
