Examples

muBrain <- readRDS(unzip(system.file("extdata", "muBrainSubset_SpatialOverlay.zip", 
                                    package = "SpatialOmicsOverlay")))

samp <- which(sampNames(muBrain) == "DSP-1012999073013-A-F12")

ROIMask <- createMask(b64string = position(overlay(muBrain))[samp], 
                      metadata = meta(overlay(muBrain))[samp,],
                      outline = TRUE)
