LymAnalyzer: a tool for comprehensive analysis of next generation sequencing data of T cell receptors and immunoglobulins

Yaxuan Yu, Rhodri Ceredig, Cathal Seoighe
2015 Nucleic Acids Research  
Although, to date we have applied it to TCR/IG data from human and mouse, it can be applied to data from any species for which an appropriate database of reference genes is available.  ...  In order to provide protection from a wide range of pathogens, these cells display highly diverse repertoires of IGs and TCRs.  ...  Given that TCR/IG sequencing data sets are tractable on a personal computer for typical data sets or on computer clusters for large projects this trade off is unnecessary.  ...
