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.
You can install kbkdna from PyPI using pip:
$ pip install kbkdna
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%
