— 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.
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
