Snap, gene prediction
Snap, gene prediction
Snap, gene prediction uses splicing information from different species to find transcript and coding sequences within a genome assembly. Snap takes a fasta DNA sequence file and produces a protein sequence file and a transcript sequence file, both in fasta format.
Quick Start
- To use Snap, gene prediction, import your assembly in fasta format. Then select a hmm file from a similar species.
