Re: [Freesurfer] R: Re: FDR map: hide very little cluster

just use the FDR thresholded input and set --thmin to 0.5

Thanks. But I do not know how I can obtain a corrected sig.nii.gz. In this way I have obtained only summary.txt. If I add --vwsig vwsig cds file is request.

Use the --minarea option to mri_surfcluster (not the CSD).

Hi list,
please, could you help me because from several days I'm trying to have a solution.
I have performed a seed-based fcMRI analysis by FAST.
After mri_glmfit, I have obtained a sig.nii.gz which contains uncorrected results.I have corrected by FDR using the graphical interface provided in tksurfur. The FDR corrected contains some very small areas (<5-10 voxels) which I would like to hide in order to  present a more clear map. How is possible to do it?I have tried with  mri_surfcluster. To have vwsig.nii.gz I should have a CSD file. But this file
could be also produced when FDR correction is applied? I'm very confused.
Thank you very much for your work.
Kind regards.
Stefano
