bwconncomp: Label Connected Clusters of Certain Size

In neuroconductor-devel/spm12r: Wrapper Functions for 'SPM' (Statistical Parametric Mapping) Version 12 from the 'Wellcome' Trust Centre for 'Neuroimaging'

Label Connected Clusters of Certain Size

Description

Get Cluster of certain size from spm_bwlabel

Usage

bwconncomp(
  infile,
  outfile = NULL,
  retimg = TRUE,
  conn = 26,
  reorient = FALSE,
  spmdir = spm_dir(),
  verbose = TRUE,
  install_dir = NULL
)

Arguments

infile	input filename
outfile	output filename
retimg	Return the image instead of matlab output
conn	Connections to be passed to MATLAB's bwconncomp
reorient	If retimg, then this argument is passed to readNIfTI
spmdir	(character) path for SPM12. If NULL, assumes SPM12 is in matlabpath.
verbose	Print Diagnostics
install_dir	directory to download SPM12

Value

Name of output file or nifti object, depending on retimg

Examples

library(neurobase)
set.seed(1234)
dims = c(30, 30, 10)
arr = array(rnorm(prod(dims)), dim = dims)
nim = nifti(arr)
mask = datatyper(nim > 1)
## Not run: 
cc = bwconncomp(mask)
tab = table(c(cc))

## End(Not run)
