SplitMSA

Simple FASTA file splitter. Capable of batch trimming a large amount of sequences in the form of a MSA in a FASTA file.

Features

• Split large fasta files that contain a multiple sequence alignment (MSA) into individual genes
• Trim off stop codon
• Batch process multiple genes from one MSA
• Correct gene start and stop locations based on start and stop codon location
• Catalogues errors that occurred in human-readable CSV file

Planned

• Translate MSA into amino acids while maintaining alignment (shows type of mutation if frameshift)
• Simple to use GUI
• Run without system-wide python install
