mkbrainmask not finding fslmaths
by dahlia＠nmr.mgh.harvard.edu 01 Jul '09

Hi, I ran the following preproc-sess command and mkbrainmask-sess failed, with an error message of not finding fsmaths. I don't know where to be looking for this file and what previous command should have generated it. Can anyone help me out? Thanks! Dahlia. I ran: preproc-sess -sf sessid_subj31.txt -df sesspar -fwhm 5 The error message was: ERROR: cannot find either fslmaths for avwmaths ERROR: mkbrainmask failed ERROR: mkbrainmask-sess failed mkbrainmask-sess.log says: mkbrainmask-sess $Id: mkbrainmask-sess,v 1.12.2.1 2008/10/02 21:56:15 greve Exp $ Linux mbc.stanford.edu 2.6.22.9-61.fc6 #1 SMP Thu Sep 27 18:07:59 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux Tue Jun 30 11:01:46 PDT 2009 /home/dahlia.sharon/functionals/fba_study_mtloc -maskstem brain -fsd bold -s mtloc_19may07 -d /home/dahlia.sharon/functionals/subj31 -update This is the command preproc-sess invoked: mkbrainmask -i 025/f.bhdr -o masks/brain.nii -thresh 0.1 -ndil 1 -nerode 0 The data is not on the network so I can't give paths.

Multiple Comparison - Clusterwise Correction
by Devdutta W 01 Jul '09

01 Jul '09

Hi Freesurfers, More questions about this analysis. 1) Referring to the documentation, we used the following command: tksurfer fsaverage lh inflated -annot mc-z.abs.2.sig.ocn.annot -fthresh 2 -curv -gray The documentation says we should see an image as shown in Figure 1 (attached). But what we see is Figure 2 (also attached). Can somebody explain this? 2) When running the simulation does it matter what threshold we use? For example, can we use a threshold of 2 or 3 (instead of 4 as shown in documentation) when running mri_glmfit-sim? And do we have to use the same threshold while displaying the clusters after? Thanks for any help. Devdutta
