Members of the iReceptor team are hacking throughout the weekend on a project called “Adaptive ImmunoSeq Repository as part of the ./hackseq-rna virtual COVID-19 Ultra Hackathon. Microsoft and Adaptive Biotechnologies are exploring how the immune system responds to COVID-19 and the 3 day goal is to develop a tool to query the Adaptive ImmunoSeq repository (using their WebAPIs), download data, and convert it to the standard AIRR-seq data formats for Repertoires and Rearrangements.
