Dear Freesurfer's experts,

In order to have a robust PET signal projection, is it possible compute the projected PET signal as a weighted average of the PET signal intersecting with the surfaces ranging from 35 to 65% of the cortical tickness with a step t=5% ?

More weight would be given to the surfaces located near the mid distance between the pial and white surfaces as they have a higher probability to be well located within the cortex (using a normal distribution for example).

Thank you for helping.

Best,

Matthieu
