Analysis of Alternative Splicing

 

Description

JETTA is an integrated software tool for gene and exon expression calculation and alternative splicing analyses. It can be applied to the analysis and visualization of both exon-junction array and RNA-Seq data.

Microarray Libraries and Annotations

 

JETTA supports the GG-H arrays (Xu et al, PNAS, 2011) as well as all Affymetrix exon and exon-junction arrays for any species. Here, the libraries for some selected platforms are downloadable. For other Affymetrix platforms, the required library files for JETTA analyses (chip layout file, probe group file, TC meta probeset file and alternative spcliing structure file) will be available in Affymetrix wesite. For other third party arrays or custom arrays, feel free to contact us for supports.
