Hi Ben & colleagues,

This thread and the developers manual are really helpful when adding custom atlases to WFU Pickatlas.

I am trying to add the new AAL3 atlas based on the steps in the developers manual, and my only problem is that the voxel size for my AAL3.nii file is [-2 2 2] compared to [2 2 2] for the MNI_T1 template file provided with Pickatlas, causing the dimensions to disagree.

This is probably easy to fix (does it have anything to do with flipping), but could you please point me to the right solution?

Thanks very much in advance!

Best wishes,

Lukas
