WebJun 12, 2012 · In my experience, the smoothness estimates of 3dFWHMx on the ResMS.hdr file and SPM's smoothness estimations (stored in SPM.xVol.FWHM, in mm) give similar results. Also, be aware that older versions of 3dFWHMx underestimate smoothness and lead to increased false positives. This is because the smoothness at the group level is … WebAug 9, 2012 · We’re using AlphaSim to estimate a cluster extent threshold for our group maps, and a reviewer for one of our articles suggested that we must used 3dFWHMx to estimate the true smoothness in X, Y, and Z rather than just putting the size of the blur we applied to the data (using the -FWHM option).

It might be applicable in this case since the ResMS.nii image is a single volume, but in my experience the difference is negligible between including the 2difMAD option and omitting it, at least for fMRI data.

WebHello, I would like to use AlphaSim in REST, but am not clear on how it determines the smoothness of data in a given ROI. If I understood it correctly, prior to using AlphaSim in AFNI, the residual time series from a given GLM are run through 3dFWHMx program to determine the data FWHM. android 10 usb connection settings http://restfmri.net/forum/frontpage?destination=frontpage&form_build_id=form-530fe5e42d6e59bf764582ee87522f80&form_id=user_login_block&name=780&page=737 bad constant germany
