ClusterMarkersOfAllCells¶

Markers for clusters of all cells.

See also ClusterMarkers.

Input¶

• srtobj: The seurat object loaded by SeuratPreparing If you have your Seurat object prepared by yourself, you can also use it here, but you should make sure that the object has been processed by PrepSCTFindMarkers if data is not normalized using SCTransform.
  

Output¶

• outdir: Default: {{in.srtobj | stem0}}.markers.
  The output directory for the markers and plots

Environment Variables¶

• ncores (type=int): Default: 1.
  Number of cores to use for parallel computing for some Seurat procedures.
  
  • Used in future::plan(strategy = "multicore", workers = <ncores>) to parallelize some Seurat procedures.
    
  • See also: https://satijalab.org/seurat/articles/future_vignette.html
• group_by: The column name in metadata to group the cells.
  If only group_by is specified, and ident-1 and ident-2 are not specified, markers will be found for all groups in this column in the manner of "group vs rest" comparison.
  NA group will be ignored.
  If None, Seurat::Idents(srtobj) will be used, which is usually "seurat_clusters" after unsupervised clustering.
  
• dbs (list): Default: ['KEGG_2021_Human', 'MSigDB_Hallmark_2020'].
  The dbs to do enrichment analysis for significant markers See below for all libraries.
  https://maayanlab.cloud/Enrichr/#libraries
• sigmarkers: Default: p_val_adj < 0.05 & avg_log2FC > 0.
  An expression passed to dplyr::filter() to filter the significant markers for enrichment analysis.
  Available variables are p_val, avg_log2FC, pct.1, pct.2 and p_val_adj. For example, "p_val_adj < 0.05 & abs(avg_log2FC) > 1" to select markers with adjusted p-value < 0.05 and absolute log2 fold change > 1.
  
• enrich_style (choice): Default: enrichr.
  The style of the enrichment analysis.
  The enrichment analysis will be done by EnrichIt() from enrichit.
  Two styles are available:
  
  • enrichr: enrichr style enrichment analysis (fisher's exact test will be used).
    
  • clusterprofiler: clusterProfiler style enrichment analysis (hypergeometric test will be used).
    
  • clusterProfiler: alias for clusterprofiler

• subset: An expression to subset the cells for each case.
  
• cache (type=auto): Default: /tmp.
  Where to cache the results.
  If True, cache to outdir of the job. If False, don't cache.
  Otherwise, specify the directory to cache to.
  
• rest (ns): Rest arguments for Seurat::FindMarkers().

  Cases for investigating the overlapping of significant markers between different cases or comparisons.

  There are two situations that we can perform overlaps:
  
  1. If ident-1 is not specified, the overlaps can be performed between different comparisons.
     
  2. If each is specified, the overlaps can be performed between different cases, where in each case, ident-1 must be specified.
