toolkitbio 1.0.8

A bioinformatics toolkit for DNA sequence analysis, FASTA/GenBank file operations, NCBI queries, sequence alignment, phylogenetics, and protein structure visualization.

🧬 toolkitbio

A comprehensive Python bioinformatics toolkit for DNA sequence analysis, file format conversion, NCBI queries, sequence alignment, phylogenetics, and protein structure visualization.

Installation

pip install toolkitbio

Features

Module	Description

Quick Start (Python API)

from toolkitbio import dna_operations, read_fasta, fetch_from_ncbi

# DNA operations
result = dna_operations("ATGCTAGCTAGCTAGCTG", start=3, end=11)
print(result["rna"])       # RNA sequence
print(result["protein"])   # Protein sequence

# Read FASTA file
records = read_fasta("sequences.fasta")

# Fetch from NCBI
data = fetch_from_ncbi("NM_001301717")
print(data["organism"], data["length"])

Command-Line Interface

# DNA sequence operations
toolkitbio seq-ops --seq ATGCTAGCTAGCTAGCTG

# Read FASTA file
toolkitbio read-fasta sequences.fasta

# Fetch from NCBI
toolkitbio fetch-ncbi NM_001301717

# Pairwise alignment
toolkitbio align-pair --seq1 AGTACACTGGT --seq2 AGTACGCTGGT

# Convert FASTA to GenBank
toolkitbio convert input.fasta output.gb

# Build phylogenetic tree
toolkitbio phylo-tree aligned.fasta --method upgma

# View 3D protein structure
toolkitbio view-pdb 1A3N --save structure.png

Requirements
