Hello
In the past, the advice given for applying a SVC (small volume correction) has been to try and match the expected effect size. A spherical volume with radius 8 to 16mm has usually been quoted.
I am wondering if there is a maximum and minimum radius for a spherical SVC e.g. can we go up to 30mm or down to 5mm radius without violating any gaussian field assumptions or does it not matter?. Also, does the optimum spherical radius depend upon the degree of smoothing?
Thanks
