protfasta

Release 0.1.12 (March 2023)

Overview

protfasta - a robust parser for protein-based FASTA files.

Documentation

For all documentation see https://protfasta.readthedocs.io/en/latest/.

For code see https://github.com/holehouse-lab/protfasta.

Installation

protfasta has been tested on Linux and macOS. It should also work on Windows but we haven't tested it there yet.

protfasta can be downloaded and installed directly from PyPI using pip:

pip install protfasta

If this has worked, the pfasta command-line tool should be available from the command-line

pfasta --help

And you're done. This also means you can now import and use protfasta in your Python workflow.

Simple example

import protfasta

# sequences is now a dictionary where keys are FASTA headers and values are sequences.
sequences = protfasta.read_fasta('inputfile.fasta')

Errors and help

For bug reports or errors please raise an issue on this github repository (see the Issues tab at the top).

Changelog

• 0.1.12 (March 2023) - integrated in check_header_parser flag via pull request from the amazing Friedlab !

• Added in append_to_fasta flag so you can append to an existing FASTA file (thanks Ryan!)

• 0.1.11 (Sept 17th 2022) - re-wrote code for checking duplicate sequence to make it O(1) instead of O(n) for number of sequences (:-/) and added convert-remove option for invalid_sequences

• 0.1.9 (Sept 12th 2021) - added in robustness for whitespace in sequence files, which, bizarrely, was not present (i.e. added as an invalid residue type but can now be converted).
