Arguments

Argument	Description
gobject	giotto object
spat_unit	spatial unit
feat_type	feature type
expression_values	feat expression values to use
cluster_column	clusters to use
method	method to use to detect differentially expressed feats
subset_clusters	selection of clusters to compare
group_1	group 1 cluster IDs from cluster_column for pairwise comparison
group_2	group 2 cluster IDs from cluster_column for pairwise comparison
min_expr_gini_score	gini: filter on minimum gini coefficient for expression
min_det_gini_score	gini: filter minimum gini coefficient for detection
detection_threshold	gini: detection threshold for feat expression
rank_score	gini: rank scores to include
min_feats	minimum number of top feats to return (for gini)
min_genes	deprecated, use min_feats
group_1_name	mast: custom name for group_1 clusters
group_2_name	mast: custom name for group_2 clusters
adjust_columns	mast: column in pDataDT to adjust for (e.g. detection rate)
...	additional parameters for the findMarkers function in scran or zlm function in MAST

Details
