## scHOT_performPermutationTest

### Description

Perform permutation test

### Usage

    scHOT_performPermutationTest(
      scHOT,
      verbose = FALSE,
      parallel = FALSE,
      BPPARAM = BiocParallel::SerialParam()
    )

### Arguments

`scHOT` | A scHOT object
`verbose` | A logical input indicates whether the intermediate steps will be printed
`parallel` | A logical input indicates whether run the permutation test using multiple cores in parallel.
`BPPARAM` | A `BiocParallelParam` class object from the `BiocParallel` package is used. Default is SerialParam().

### Value

scHOT A scHOT object with results stored in scHOT_output slot

### Examples

     sce_MOB_subset <- MOB_subset$sce_MOB_subset
     scHOT_spatial <- scHOT_buildFromSCE(sce_MOB_subset,
