NCI ITCR #5U24CA180996

Infrastructure for analysis of multimodal data

• Parent grant (completed August 2019)– MultiAssayExperiment and data resources– RaggedExperiment– Form a basis for much of the multimodal data

analysis in Bioconductor

• Renewal grant– Extensions to single-cell multimodal data– Leveraging Bioconductor for variant prioritization– Performant computing and education
