Updates

  • 10/12/2012
    • Release of MATS 3.0.3.beta,
      • Fixed a bug related to gene expression level calculation.
  • 8/30/2012
    • Release of MATS 3.0.2.beta,
      • Fixed a bug related to default insert sizes and standard distribution.
  • 8/24/2012
    • Release of MATS 3.0.1.beta,
      • A bug related to Ubuntu (tested on 12.04) is fixed.
  • 8/9/2012
    • Release of MATS 3.0.0.beta, a major update with important features added to MATS:
      • Replicate data support: MATS now works with replicate RNA-Seq data from both paired and unpaired study design.
      • Improved filtering system: MATS now filters out AS events where large gene expression fold changes may confound the analysis.
      • MacOS support: MATS now supports both Linux and MacOS (tested on MacOS 10.8.1).
  • 5/25/2012
    • Release of MATS 2.1.0
      • MATS now works with both read sequence files (fastq) and mapped reads files (bam). Using bam files adds flexibility in mapping because MATS will skip the read mapping step.
      • A bug related to an empty AS event file is fixed.
  • 5/15/2012
    • Release of MATS 2.0.0, a major update with important features added to MATS:
      • Simplified running procedure: MATS now only requires the raw RNA-Seq data, a genome sequence file, and a gene/transcript annotation file in GTF format as the input.
      • Ability to analyze different types of alternative splicing events: MATS now automatically detects and analyzes alternative splicing events corresponding to all major types of alternative splicing patterns.
      • Improved statistical power: MATS now works with both exon-exon junction reads and exon body reads which leads to improved statistical power.
  • 3/5/2012
    • Release of MATS 1.2.0, added a new method to calculate P-values by likelihood-ratio test, which is ~100x faster than the Bayesian method.
  • 2/16/2012
    • Release of MATS 1.1.0, adds Ensembl version of mouse annotation.
  • 12/15/2011
    • Release of MATS 1.0.0, the initial version of MATS was opened.

About MATS

MATS is a computational tool to detect differential alternative splicing events from RNA-Seq data. The statistical model of MATS calculates the P-value and false discovery rate that the difference in the isoform ratio of a gene between two conditions exceeds a given user-defined threshold. From the RNA-Seq data, MATS can automatically detect and analyze alternative splicing events corresponding to all major types of alternative splicing patterns. MATS handles replicate RNA-Seq data from both paired and unpaired study design.
