fastahack
utility for indexing and sequence extraction from FASTA files
Description
fastahack is a small application for indexing and extracting sequences and subsequences from FASTA files. The included Fasta.cpp library provides a FASTA reader and indexer that can be embedded into applications which would benefit from directly reading subsequences from FASTA files. The library automatically handles index file generation and use. Features: * FASTA index (.fai) generation for FASTA files
* Sequence extraction
* Subsequence extraction
* Sequence statistics (currently only entropy is provided)
Sequence and subsequence extraction use fseek64 to provide fastest-possible
extraction without RAM-intensive file loading operations. This makes fastahack
a useful tool for bioinformaticists who need to quickly extract many
subsequences from a reference FASTA sequence.Upload more screenshots
