tRNAnalysis 0.1.8

tRNAnalysis : this software will perform alignment of reads to tRNA

tRNAnalysis

This workflow was generated as a response to not being able to effectively analyse tRNA data from next generation sequencing experiments rapidly and robustly. Typical workflows are not very flexible and do not scale well for multiple samples. Moreover, most do not impliment best-practice mapping strategies or generate detailed analysis reports to aid biological interpretation.

Our pipeline can be used for evaluating the levels of small RNAs in a sample, but provides detailed analysis of tRNAs, with particular emphasis on tRNA fragment analysis.The pipeline is in constant development and further features will be added in the future. For example, we will extend our pipeline to perform detailed anaysis of miRNAs and plan to write an R shiny framework for interactive report features.

Installation

Conda installation

The preferred method for installing tRNAnalysis is through Conda. However, at the moment we are experiencing issues with a broken dependancy so I would suggest either installation using pip and manually install dependancies (although there are a lot) or more easily, use the linux environment in the Conda environment section.

To install trnanalysis using conda::

conda install -c bioconda trnanalysis

Conda environment

Conda is an awesome project, however it can suffer from significant issues relating to how long it takes the solver to fix installation issues. For more information regarding these conda issues please see bioconda issues.

In order to try and speed things up we have provided a conda environment for installation. Currently only linux is supported and it can be installed by doing the following::

wget https://raw.githubusercontent.com/Acribbs/tRNAnalysis/master/conda/environments/trnanalysis-linux.yml
conda env create -f trnanalysis-linux.yml 
conda activate trnanalysis-env

Pip installation

trnanalysis can also be installed using pip::

pip install trnanalysis

Manual installation

Alternatively, you can manusally install tRNAnalysis by::

git clone https://github.com/Acribbs/tRNAnalysis.git
cd tRNAnalysis
python setup.py install
trnanalysis --help

Usage

Run the trnanalysis --help command view the help documentation for how to run tRNAnalysis.

To run the main trnanalysis pipeline run::

trnanalysis trna make full -v5

In order to run and generate the multiQC report to identify read quality and Rmarkdown html report for the tRNA analysis run::

trnanalysis trna make build_report -v5

Running locally or on a cluster - the default setting to run trnanalysis is on a cluster, with SLURM, SGC, Torque and PBS/pro currently supported. However, if you dont have access to a cluster then tRNAnalsysis can be executed locally by adding --no-cluster as a commandline argument.
