IsoEM2
Introduction
The IsoEM package can be used to infer isoform and gene expression levels from high-throughput transcriptome sequencing (RNA-Seq) data. IsoEM uses an Expectation-Maximization (EM) algorithm based on a probabilistic model that takes into account the fragment length distribution, with mean/standard deviations specified by the user or automatically inferred when using paired-end reads. The current version (IsoEM2) generates bootstrap-based confidence intervals for the TPM/FPKM estimates and is distributed along with the IsoDE2 package for performing bootstrap-based differential expression analysis. For details see our Bioinformatics Application Note.
Source code and sample data
The IsoEM2/IsoDE2 software is written in Java so it can be run on any platform with a Java virtual machine. See the README file for installation instructions. Wrappers for the Galaxy platform along with a sample dataset and instructions for testing the installation of IsoEM2 and IsoDE2 are also included below.
