Group gray matter density mask

Submitted by Peace on

Dear Experts

I would like to genearate a group GM mask by using DPABI's quality control module.

In my understandings, I could generate a GroupMask90Percent.nii based on wAutomask, and then thresholding the mask.

  1. How to create a group specific GM mask by using QC module?

In addition, all images must have the same dimension for statstiscal analysis.

If a group GM mask was generated using SPM Masking toolbox, and then reslicing the mask.

      2. The resliced mask looks a little bit different, how to solve this issue?

Thanks for considering my request.

Best wishes

Larry
