oldowan.mitomotifs-cmdline 1.0.0

Installation Instructions

This package is pure Python and has only pure Python dependencies (oldowan.mitomotifs and oldowan.fasta) outside of the standard library. All of these dependencies will be automatically installed if you use the setuptools easy_install tool. This usually goes something like this:

$ easy_install oldowan.mitomotifs-cmdline

or on a unix-like system, assuming you are installing to the main Python site-packages directory as a non-privileged user, this:

$ sudo easy_install oldowan.mitomotifs-cmdline

You may also use the standard python distutils setup method. You will have to download ind install oldowan.fasta and oldowan.mitomotifs first. Then, download the current source archive from the file list towards the bottom of this page, unarchive it, and install. On Mac OS X and many other unix-like systems, having downloaded the archive and changed to the directory containing this archive in your shell, this might go something like:

$ tar xvzf oldowan.mitomotifs-cmdline*
$ cd oldowan.mitomotifs-cmdline*
$ python setup.py install

Quick Start

Convert sequences to sites:

$ seq2sites sequences.fasta

Convert sequences to sites, saving the output to a file:

$ seq2sites sequences.fasta > sites.txt

Sequences must be contiguous! Separate runs of sequence, such as HVR1 and HVR2 without the intervening sequence interval, must be analyzed separately.

There is also a cutoff on the number of ambigous sites (N) allowed in the sequence. By default, this is 10 - but this is an option that can be set:

$ seq2sites --ambig-cutoff=20 sequences.fasta

Convert a list of variable sites to sequence. The input file should be a comma-seprated-values list with one entry per line, with name, N, and sites. Sites should be separated by whitespace:

$ cat hvr1_sites.txt
Seq1,1,16129A
Seq2,1,16129A 16223T
Seq3,2,16223T
$ sites2seq hvr1_sites.txt

The default range of sequence returned is HVR1, defined as positions 16023 to 16365 on the rCRS. All predefined ranges are:

• HVR1: 16024-16365

• HVR2: 73-340

• HVR1to2: 16024-340

• coding: 577-15992

• all: 1-16559

So, to convert a list of HVR2 sites to sequence:

$ sites2seq --region=hvr2 hvr2_sites.txt

An arbitrary range may be selected. If the stop value is smaller than the start, it is assumed that the range runs through the origin:

$ sites2seq --begin=16024 --end=340 dloop_sites.txt

The rCRS sequence will can be selected with ‘rCRS’ as the sites value:

$ cat sites.txt
Seq1,1,rCRS
Seq2,1,16129A 16223T
