Explore an Expression Matrix by viewing a sortable heatmap of selected conditions.
This method allows you to view and explore expression data as a sortable heatmap. The conditions/samples are displayed on each row with some summary statistics averaged across the selected features. The conditions can be sorted by those values. Each of the selected features is represented in a simple heatmap in the table. Mouse over the heatmap to view specific expression values.
The input is a .tsv file with "gene-id" listed in the A1 cell, the gene ids listed in the A column, the sample/conditions identifiers in the 1 row, and expression values that correspond to the gene-ids and sample throughout. For a comprehensive guide to formatting your expression data for import into KBase, see the Data Upload/Download Guide.
