+version: 1.17.1
+doi: 10.1371/journal.pcbi.1011324
+abstract: SingleCellMultiModal is an ExperimentHub package that serves multiple datasets
+  obtained from GEO and other sources and represents them as MultiAssayExperiment
+  objects. We provide several multi-modal datasets including scNMT, 10X Multiome,
+  seqFISH, CITEseq, SCoPE2, and others. The scope of the package is is to provide
+  data for benchmarking and analysis.
