How to add atlas in DPABI_VIEW?

I am trying to locate the position of some brain structures in DPABI_VIEW with the atlas provided.

However, existing atlas can only show rough structures while I want the position of some fine structures.

I tried to find some atlas on the internet whose file format are ".nii", but DPABI_VIEW needs both ".nii" file and ".mat" file to successfully add an atlas.

I wonder how I can succefully add an atlas to DPABI_VIEW and if there is any recommended website for me to easily find suitable atlas and corresponding “.mat" file.

Then you have to make ".mat" by yourself. Open one and find the structure.
