Description

MSA4U is a simple visualisation tool for Multiple Sequence Alignments.

Input format: Multiple sequence alignments or unaligned sequences in fasta format.
Output: MSA plot in vector format (pdf)
In case of unaligned sequences as input msa4u uses MAFFT with --auto option to build MSA.

Source code and documentation are available at the GitHub Page.
