Crate seqtui 

SeqTUI - Terminal Alignment Viewer

A terminal-based viewer for FASTA sequence alignments using ratatui.

Architecture

The application follows an event-driven architecture with clear separation:

• model: Data structures for sequences, viewport, and application state
• fasta: FASTA file parsing and validation
• formats: Multi-format parsing (FASTA, PHYLIP, NEXUS)
• event: Keyboard event handling (Vim-style navigation)
• ui: TUI rendering with ratatui
• controller: Orchestration of state transitions
• genetic_code: NCBI genetic codes and translation logic

Supported File Formats

• FASTA (.fasta, .fa, .fna, .faa)
• PHYLIP (.phy, .phylip) - sequential and interleaved
• NEXUS (.nex, .nexus, .nxs)
