Application Details

  • Description: Trans-ABySS (Assembly By Short Sequences) is a software pipeline written in Python and Perl for analyzing ABySS-assembled transcriptome contigs.
  • Version: 1.5.4
  • Modules: transabyss/1.5.5
  • Licence: BCCA (BC Cancer Agency) academic use


This pipeline can be applied to assemblies generated across a wide range of k values. It first reduces the dataset into smaller sets of non-redundant contigs, and identifies splicing events including exon-skipping, novel exons, retained introns, novel introns, and alternative splicing. The Trans-ABySS algorithms are also able to estimate gene expression levels, identify potential polyadenylation sites, as well as candidate gene-fusion events [1]

Because of the nature of such tasks, it may be more appropriate to use highmem nodes rather than standard compute nodes.
