kbkdna 0.0.0

Simple tools for working with DNA

When doing biology, sometimes you just need to quickly know how long a DNA sequence is, or what its reverse complement is. There are lots of tools out there that can tell you these things, but they often do a lot more than that too and can be overkill for really quick questions. In contrast, this package provides an easy-to-use command-line app that’s just designed to give simple answers to simple questions.

Installation

You can install kbkdna from PyPI using pip:

$ pip install kbkdna

Usage

The command-line application that gets installed is called dna. You can use the --help flag to get information on the kinds of things it can calculate:

$ dna --help

You can use the len command to get the length of a DNA sequence:

$ dna len CATCTAATTCAACAAGAATT
20

You can use the rc command to get the reverse complement of a DNA sequence:

$ dna rc CATCTAATTCAACAAGAATT
AATTCTTGTTGAATTAGATG

You can use the gc command to calculate the GC content of a DNA sequence:

$ dna gc CATCTAATTCAACAAGAATT
25.0%
