Re: [Freesurfer] FDR in FS-FAST

Hi list, I have two concerns, please:

1. It is possible to apply FDR correction on rs-fMRI seed based

analysis by FS-FAST? If yes, I can I do it?

try this binary ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_fdr

2. I have apply the FS guidelines and I have used Montecarlo

correction with threshold at 1.3 but in the within group analysis the clusters are very large. In the guide I read examples with a threshold at 3. Is there a specific reason?

There is not a hard-and-fast criteria for the voxel-wise threshold. 3 is fine as is 1.3

Thanks
