WebPseudo-bulk functional analysis. When cell lineage is clear (there are clear cell identity clusters), it might be beneficial to perform functional analyses at the pseudo-bulk level instead of the single-cell. By doing so, we recover lowly expressed genes that before where affected by the “drop-out” effect of single-cell. WebScanpy already provides a solution for Visium Spatial transcriptomics data with the function scanpy.read_visium() but that is basically it. Here in Squidpy, we do provide some pre-processed (and pre-formatted) datasets, with the module squidpy.datasets but it’s not very useful for the users who need to import their own data.
