Orange at ISMB/ECCB 2019

Our entry to this year’s largest bioinformatics conference was on the training of single-cell data analytics. We claim that with Orange and its new single-cell RNA analysis add-on, one can assemble a workshop to teach essential concepts from single-cell analytics in a single day. Single-cell genomics is driven on revolutionary technology from molecular biology that allows us to peek into inner workings of the individual cell. Single-cell datasets feature thousands of genes and cells and benefit from the analysis that integrates this data with other knowledge sources, like those on the classification of genes, lists of pathways, and sets of cell-type markers.
