We will go through the main concepts of GSEA to get a feeling of how it works and the differences with Over-Representation Analysis methods (ORA).
Hope you like it!

Great material! Do you know of any topology-based methods that works on single-cell datasets (or pseudo-bulk single cell data)?
-
Great video! Really helpful for getting an understanding of the analysis workflow! A small critique / suggestion for improvement that I think could be made is in terminology being used, specifically referring to genes in the ranked list as being overrepresented. As you said in the video, one is not filtering any genes, so when looking at your gene set in GSEA, you aren't looking at the proportion of the genes being part of your list, but rather where are the genes located in the unfiltered ranked list containing all the genes.
