Random Field Theory

Submitted by janR on
Dear Yan, It is possible in REST, to correct for multiple comparisons at the cluster level using Gaussian random field theory. I've noticed other programs such as FSL FEAR pre-select Z threshold and use cluster size as a determining significance factors (e.g. min Z >2.3; cluster significance: p < 0.05, corrected). Can such an approach also be adopted in REST? Regards, Jan R

Hi! Good point. Actually, this has been done and will be integrated into REST in the next release. Currently, just have a taste from http://www.restfmri.net/forum/Programs_YAN 6. Program for performing Gaussian Random Field theory multiple comparison correction like easythresh in FSL: y_GRF_Threshold.m Best, Chao-Gan
