Dear FS Experts,

I would like to show the distribution and overlap of lesions on an average inflated brain surface as a heat map.

I have a 150 subjects of which I’ve made masks of T2 lesions and moved into their respective subject-T1w-spaces (using T1.mgz as reference) where I have completed recons.

What are the steps in bringing these subject-T1w-space lesions into an average brain and presenting them as a surface? Again, I hope to show the lesion distribution scaled by the number of times (out of 50 subjects) that any voxel is a lesion.

Thanks in advance,

Mitch
