Based on previous work (see : https://github.com/mszinte/pRF_analysis/blob/main/analysis_code/postproc/prf/postfit/compute_css_pcm.py) we want to apply a similar way to compute pRF CM on the HCP data_set
TO DO :
- acces HCP data
- understand strucuture of HCP data and neuropythy
- compute CM for vertex in V1 :
- compute geodesic distance between neibors vertex
- compoute visual distance between pRF centers
