Thank you Doug.I run permutations with mdi_glmfit-sim --sim perm. Would you be able to advice on the output and how to open the permutation outputs? The tutorial instructs on how to open the *.summary file for the summary of clusters and *.sig.cluster.mgh the cluster corrected map, but not the permutation output.Thank you, Pablo Date: Fri, 7 Aug 2015 10:53:55 -0400 From: gr...@nmr.mgh.harvard.edu To: freesurfer@nmr.mgh.harvard.edu Subject: Re: [Freesurfer] Correction for multiple comparisons - qdec
You can try permutation, though it is often more constraining than those other two options. To do this, you'll need to run mri_glmfit-sim from the command line using the --sim perm option. Run it with --help to get examples On 8/7/15 6:59 AM, pablo najt wrote: Dear FS experts, I have a question about running corrections for multiple comparisons. I am finding a fairly large cluster analyzing 2 groups on sulcal depth. However when I tried FDR or cluster wise correction the results do not seem to survive. As the result is on the region I was predicting I want to make sure there are no other options for correcting for multiple comparisons. I am including a figure of my result to give you an idea of the size of the cluster. Do you have any suggestions for trying alternative ways of correcting?
