Blst2gm

# 2) Feed the result into range-oriented downstream helpers
cat smear.asn | blst2gm | gm2ranges

# 3) Inspect the compact columns directly
cat smear.asn | blst2gm | column -ts $'\t'

Recommended Workflow

1. Start from BLAST annotation data in the structure expected by the wrapper's xtract recipe.
2. Pipe that stream into blst2gm and inspect the emitted accession, score, starts, lengths, and strand fields.
3. Continue into gm2ranges or gm2segs if you need interval normalization or segment reporting.
4. Keep the original BLAST annotation source around if you may need richer metadata later.

Guardrails

• The wrapper has no option parsing or built-in help path.
• Empty stdin fails with the underlying xtract error No data supplied to xtract from stdin or file.
• The source recipe explicitly filters for annotations labeled BLASTN - mrna; other BLAST types are ignored.
• Output fields are condensed with pipe-separated multi-value columns rather than expanded row-per-segment tables.
• The wrapper depends on xtract being on PATH.
