The TCRex webtool allows functional interpretation of full human T-cell repertoire data derived from next generation sequencing.

TCRex is the first tool of its kind and is able to link T-cell receptor sequences to a rapidly expanding list of 49 different important immunogenic epitopes, consisting of 44 viral and 5 cancer epitopes. Additional epitopes can be added by users for their own use. The tool is able to calculate enrichment statistics and baseline prediction rates to evaluate full repertoires. It is unique among TCR-epitope prediction tools in that it allows processing of full human repertoires. It has also brought together the largest database on TCR-epitope data to train the underlying machine learning models through manual curation of various online resources and scientific literature.

TCRex was developed at the University of Antwerp and has been released for public use in 2018. The manuscript describing the webtool is available as a preprint in BioRXiv.  TCRex can also be followed on Twitter: @TCRexTool.
