 `match_CellMatch`
 For large datasets containg > 10,000 cells or > 15 clusters, it is strongly recommended to set match_CellMatch 'TRUE' to match CellMatch database first to include potential marker genes in terms of large system memory it may take.
 
 `cancer`
-If match_CellMatch is set TRUE and the sample is from cancer tissue, then the cancer type may be defined. Select one or more related cancer types in 3.2 of Details for human and 3.2 of Details for mouse. The dafult is NULL for tissues without cancer.
