Convert plain text sequence files to FASTA format in one command

pip install indiestack

A Python CLI tool that converts plain text sequence files (one sequence per line) to standard FASTA format. Validates DNA and protein sequences, auto-generates headers, and wraps lines to the standard 80-character FASTA width. Built because every online converter was paywalled or required uploading sensitive research data to a third party.
