WebDetails When merging Seurat objects, the merge procedure will merge the Assay level counts and potentially the data slots (depending on the merge.data parameter). It will also merge the cell-level meta data that was stored with each object and preserve the cell identities that were active in the objects pre-merge. Webseuratobject <- SetAllIdent (seuratobject, id='chosen.resolution') Then run: Seurat::BuildClusterTree () Seurat::FindAllMarkersNode () Assessing the cluster markers for each node will hopefully give you a good idea on which clusters should be combined.
