SeqTUI is a fast terminal-based viewer and command-line toolkit for sequences. View, translate, convert (to FASTA), and combine sequences aligned or not — all from the terminal.
This is free and open source software.
Features include:
- Multi-Format Support: FASTA, PHYLIP, and NEXUS formats with auto-detection.
- Color-Coded: Nucleotides and amino acids displayed with distinct background colors.
- NT → AA Translation: 33 NCBI genetic codes, handling ambiguity codes (R, Y, N).
- Concatenation & Supermatrix: Combine multiple alignments, fill missing with gaps.
- SNP Extraction: Export isolated biallelic SNPs to VCF with flanking distance filter.
- Sticky Names: Sequence identifiers remain visible while scrolling.
- Vim-style Navigation: h/j/k/l, w/b/e, Ctrl+U/D, search with / and ?.
- Command-Line Mode: Batch convert, translate, combine — pipe-friendly output.
- Large File Support: Tested on alignments larger than 500 MB.
