pyrpipe: python rna-seq pipeliner

Introduction

pyrpipe (Pronounced as "pyre-pipe") is a python package to easily develop RNA-Seq analyses workflow by integrating popular RNA-Seq analysis programs in an object oriented manner. pyrpipe can be used on local computers or on HPC environments to manage analysis of RNA-Seq data. Users can use the easy-to-use APIs to popular bioinformatic tools provided with pyrpipe, or can use the methods provided in the pyrpipe_engine module to integrate any other third-party program in their pipeline.
