BioSeq Analyzer\n\nA small DNA FASTA sequence analyzer I built while learning basic bioinformatics workflows with **Biopython**.\nIt reads FASTA files and prints a short report (length, GC%, base counts, transcription/translation previews).\nIt can also export results to **JSON** and **CSV**.\n\n## What it does\n\n- Parse DNA FASTA files (Biopython `SeqIO`)\n- Base counts: A/C/G/T/N (+ common IUPAC ambiguity codes if present)\n- GC%, AT%, N%\n- mRNA preview (T → U)\n- Reverse complement preview\n- Protein translation previews (frames 1/2/3)\n- CLI tool: `bioseq`\n- Unit tests + GitHub Actions CI\n\n## Quickstart (Windows)\n\n    python -m venv .venv\n    .\\.venv\\Scripts\\activate\n    pip install -e .\n    pip install pytest\n\nRun on the example file:\n\n    bioseq --all --json report.json --csv report.csv\n\nRun tests:\n\n    pytest -q\n\n## Quickstart (Linux / macOS)\n\n    python3 -m venv .venv\n    source .venv/bin/activate\n    pip install -e .\n    pip install pytest\n\n## Usage\n\nAnalyze a FASTA file:\n\n    bioseq path\\to\\your.fasta --all\n\nSee all options:\n\n    bioseq --help\n\n## Output example\n\n    --- BioSeq Analyzer Report ---\n    Record ID        : Example_DNA_1\n    Length           : 39 bp\n    GC%              : 56.41\n    Counts           : {'A': 9, 'C': 8, 'G': 14, 'T': 8, 'N': 0}\n    Protein f1 (20)  : MAIVMGR*KGAR*\n    -----------------------------\n\n## Notes / Limitations\n\n- This is a learning project (not a full bioinformatics pipeline).\n- Large FASTA files may take time because records are currently loaded into memory.\n- If sequence length is not a multiple of 3, Biopython may warn about partial codons.\n\n## Project structure\n\n    src/bioseq_analyzer/   # package code\n    tests/                 #
