A library for structured flu sequence analysis

flua

Note: This project is under active development. APIs may change without notice.

Influenza A sequence analysis toolkit.

(Current) Features

• Load and parse influenza A FASTA files
• Automatic sequence type detection (DNA / RNA / Protein)
• Subtype extraction from FASTA headers (e.g. H1N1, H5N1pdm09)
• Segment identification (PB2, PB1, PA, HA, NP, NA, MP, NS)
• Translation with alternative product generation (splicing, frameshift, alt-ORF)
• DataFrame export for multi-sample comparative analysis

Installation

pip install -e ".[dev]"

Usage

from flua import load_fasta, groups_to_dataframe, load_multiple_fasta

group = load_fasta("sample.fasta")
print(group.subtype)  # e.g. "H1N1"

groups = load_multiple_fasta(["sample1.fasta", "sample2.fasta"])
df = groups_to_dataframe(groups, value_type="translated")
