The tsRFinder is a lightweight, fast and reliable tool for prediction and annotation of tRNA-derived small RNAs using next-generation sequencing data.
The tsRFinder depends on:
-
Perl, v5.10.1 or higher.
-
R, v2.15.2 or higher.
-
bowtie, v1.0.0 or higher.
-
tRNAscan-SE, v1.3.1 or higher, optional.
You may clone tsRFinder by typing the following in the terminal:
git clone https://github.com/wangqinhu/tsRFinder.git
Alternatively, you may download it from:
https://github.com/wangqinhu/tsRFinder/releases/latest
Finally, please add tsR_dir as an environment variable:
echo export tsR_dir="/the/path/of/tsRFinder" >> $HOME/.bashrc
source ~/.bashrc
