Python tool for automated, multiserver query for disordered regions in protein sequences.
Project description
D-score
dscore
is a meta-server tool for the prediction of disordered regions in protein sequences. It works by querying several webservers and gathering the results in an easy-to-use format. All the work is automated using simple web requests where possible, falling back to webscraping with selenium
for servers without a public API.
The servers currently used are the following (follow the links for more information and references to papers):
Installation
dscore
is available on PyPi and easily installable with pip
:
pip install dscore
Firefox webdriver
To run, dscore
also requires the Firefox
webdriver to be installed. Download the latest version of the driver from the official github release: scroll down and choose the appropriate one (for example, the ...linux64.tar.gz
for a 64bit linux installation). Make sure to unzip/untar the driver and make it accessible on the PATH
enviroment variable. Here's a detailed guide on how to do this.
Usage
Note that this program works by opening a ton of firefox windows and issuing automated commands. Let it do its thing and don't get scared! :)
DISCLAIMER: dscore
relies on other webservers for its results. Some of these servers have limitations on the amount of requests per user, so you may get temporarily blocked if you submit too many sequences. Spread them out!
dscore
can be used either as a python library or from the command line. The latter has a simple interface:
dscore --help
For example, this command will run the fast
subset of servers (about 30 seconds to get results):
dscore my_proteins.fasta -o output_dir -s fast
You will find the output files inside output_dir
, including raw data in dscore format and several useful plots.
