SpliceGrapher¶
SpliceGrapher is a Python package for creating splice graphs from RNA-Seq data, guided by gene models and EST data (when available). With version 0.2.2 we introduce SpliceGrapherXT that can convert splice graph predictions into transcript predictions.
What does it do?¶
SpliceGrapher takes gene models and RNA-Seq alignments as input and predicts splice graphs as output. It accepts gene models in either GTF or GFF3 format and alignments in the popular SAM format. As an option, users may include EST alignments in PSL format from tools such as BLAT or GMAP.
SpliceGrapher Features¶
- Accepts alignments in SAM format, so you can use your favorite read mapping and spliced alignment tools. SpliceGrapher has been tested with alignments from BWA, Bowtie, PASS, Tophat and MapSplice.
- Accurate spliced-alignment filtering using SVM classifiers that recognize splice junction sequence features. We provide highly accurate classifiers for over 100 eukaryotic species.
- Generates alternative splicing statistics for any collection of splice graphs.
- Visualization of splice graphs, splice junctions, and read depth
- Use our pipelines or construct your own using SpliceGrapher’s Python modules.
