This repository contains basic standalone scripts for processing FASTA files in various ways using Biopython. Below are brief descriptions and usage examples for each script:
Usage:
# fasta_sort.py - Sort from shortest to longest sequence
python fasta_sort.py sequences.fasta sorted_sequences.fasta
# fasta_uniq.py - Removes duplicated FASTA entries or sequences
python fasta_uniq.py sequences.fasta unique_sequences.fasta
# fasta_splitlen.py - Split into new FASTA files by sequence lengths (e.g. 0-49, 50-99, 100+)
python fasta_splitlen.py sequences.fasta --lengths "50,100"
# fasta_splitevery.py - Split into new FASTA files every n entries (e.g. every 2)
python fasta_splitevery.py sequences.fasta --count 2Requirements:
pip install biopython
