t1_pn3_rf0_slice_0092_mask: Mask file for MRI slice

In dpmixsim: Dirichlet Process Mixture model simulation for clustering and image segmentation

Description

The ‘t1_pn3_rf0_slice_0092_mask.nii.gz’ defines the mask for ‘t1_pn3_rf0_slice_0092.nii.gz’, as used in the examples. The mask used here is an all-brain mask; it just removes non-brain regions, as the result of applying a brain extraction tool to the specified dataset. Other masks may be defined to select regions of interest (ROIs).

Usage

x <- premask(slicedata, subsamp=TRUE)

Format

The file ‘t1_pn3_rf0_slice_0092_mask.nii.gz’ is in gzipped NIFTI format. The R-package oro.nifti is required to read gzipped NIFTI files.
