Nomenclature of mask-files

Dear all,

in the folder Masks/WarpedMasks, for each subject, there are three different files (now exemplary for subject 001):

  • Sub_001_BrainMask_05_91x109x91.nii
  • Sub_001_WhiteMask_09_91x109x91.nii
  • Sub_001_CsfMask_07_91x109x91.nii

I wonder, what do the indices 05, 07 and 09 mean? Are they relevant for anything or is it just a compatibility question?

"default masks made from SPM5’s a priori masks, i.e., the whole brain mask (brainmask.nii) thresholded at 50%, the white matter mask (white.nii) thresholded at 90%, and the CSF mask (csf.nii) thresholded at 70%.  "
