SeqVis reads alignments in the sequential PHYLIP (.phy) format, the NEXUS (.nex) format, and the FASTA (.fasta) format.
Data (tabular data with proportions of nucleotides)
SeqVis also reads text files with comma-separated values (.csv files) with proportions of nucleotides. This feature allows users to visualise published data on nucleotide content.
Manipulation of display
The tetrahedron can be rotated in all directions, animated, and manipulated interactively; all items on display can be changed (e.g., colour, size, and visibility).
