SilkSlider

A bioinformatic program for predicting whether proteins are 'silk-like' or not.

This program was developed by Carmel McDougall and Ben Woodcroft at the Degnan Laboratory at the University of Queensland.

Installation

There are 2 methods of installing SilkSlider. The first and likely most reliable is to create a docker image using the Dockerfile provided. The second is to install the gem directly. In both cases, SignalP and TMHMM must be installed separately as licensing restrictions mean they cannot be distributed here.

Installation via Docker

To build the docker image, first download the SilkSlider code from GitHub:

$ git clone https://github.com/wwood/SilkSlider

SignalP version 3 and TMHMM version 2.0c must be downloaded separately. As of writing they are available for download for academic use from here and here respectively.

Download the signalp and TMHMM tar.Z and tar.gz files and place them in the docker subdirectory of the SilkSlider code. After doing this, the directory should have these files:

$ ls docker
Dockerfile
signalp-3.0.Linux.tar.Z
test_case.faa
tmhmm-2.0c.Linux.tar.gz

Then build the docker image:

$ cd docker
$ docker build -t silk_slider .

SilkSlider can then be run using the docker image. A test file is provided in the docker directory of the SilkSlider code:

$ docker run silk_slider test_case.faa

 INFO silk_slider: Predicted 1 out of 2 as silk-like

Installation as a rubygem

After installing Ruby (SilkSlider is tested on Ruby 2.1.2):

$ gem install SilkSlider

Also required is the SignalP 3.0 and TMHMM 2.0c programs, which need to be installed separately and available to silk_slider on the $PATH. SilkSlider is only tested on linux systems.

Given that these versions of SignalP, TMHMM and Ruby are out of date, we recommend using the Docker installation method instead. If you do wish to install using the gem, the docker/Dockerfile provides a worked example of how this is possible.

Usage

To run the program, where my.fasta is a FASTA file of protein sequences in the current directory, run:

$ docker run -v .:/data silk_slider /data/my.fasta

The -v .:/data option mounts the current directory (and therefore your my.fasta file within it) as /data in the docker container, so that the FASTA file can be accessed by the program.

The program outputs a FASTA file of all silk-like proteins.

To see the help:

$ docker run silk_slider -h
