Hi all, I was going through the FSFAST TUTORIAL from wiki( https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorial?action=highlight&v…) I got the follwoing error during mri_volcluster, "NOT Adjusting threshold for 1-tailed test ERROR: you must specify a pos or neg sign with --fwhm" I have fwhm.dat file with 4. something vlaue. Command used, [galen:odd-v-0] (nmr-std-env) mri_volcluster --in tal.rfx.osgm/osgm/sig.nii --thmin 2 --fwhmdat tal.rfx.osgm/fwhm.dat --cwpvalthresh 0.1 --mask tal.rfx.osgm/mask.nii --fsaverage --sum tal.rfx.osgm/osgm/cluster.sum --cwsig tal.rfx.osgm/osgm/cwsig.cluster.nii --out tal.rfx.osgm/osgm/sig.cluster.nii --ocn tal.rfx.osgm/osgm/ocn.cluster.nii without --fwhmdat flag, it gave me another error "ERROR: need csd with --cwsig" will appreciate for help thanks pratap ----------------------------------- FREESURFER_HOME: /usr/local/freesurfer/stable4 Build stamp: freesurfer-Linux-centos4_x86_64-stable-v4.0.1-20070927 RedHat release: CentOS release 4.4 (Final) Kernel info: Linux 2.6.9-42.0.3.ELsmp x86_64 NMR Center info (/space/freesurfer exists): machine: galen SUBJECTS_DIR: /autofs/space/galen_003/users/carl/Tutorial/buckner_data/FsFastTutorialData/FSFTUTDIR/subjects PWD: /space/galen/3/users/carl/Tutorial/buckner_data/FsFastTutorialData/FSFTUTDIR/fb1-preproc-study/group-analysis-tut/sm-gamma-fwhm5/odd-v-0

Matlab and Freesurfer
by Robert Baldwin 09 Mar '08

09 Mar '08

Hello- I am new to Freesurfer and Matlab. I have Matlab 7.4.0 installed on an Intel Mac. I just installed Freesurfer. Now when I start Matlab I get the following warnings: Warning: Name is nonexistent or not a directory: /matlab. In path at 110 In startup at 4 In matlabrc at 255 Warning: Name is non existent or not a directory: /toolbox. In path at 110 In startup at 11 In Matlabrc at 255 I have tried adding the freesurfer folder to these files to the path for matlab, but the error still occurs. Any suggestions on how to get this error to quit? Thanks! -Robert

problems

Hi, I had downloaded the freesurfer to my system (Linux Fedora Core 4) and had completed all the installation procedures. Question 1: I would like to convert analyze format to .mgz. What command line do I use? Can I type "mri_convert x249.img 001.mgz "? Question 2: When I type "recon-all -s x249 -nuintensitycor", it doesn't run and has a error" nu_correct." What would I do to resolve the problem? Question 3: It doesn't find talairach.xfm. What would I do to get the file? thanks~~ FreeSurfer problem report --------------------------------------------------------------------- FREESURFER_HOME: /usr/local/freesurfer Build stamp:

Make_average_subject
by Alexander Fornito 26 Nov '07

26 Nov '07

Hi all, I've been having problems with make_average_subject. The command and error are below. Below this is the same command with the output generated by the --debug flag. I am running version 4.0 (redhat) on Linux Debian. I'd appreciate any help on this.

Qdec covariates
by Alexander Fornito 31 Oct '07

31 Oct '07

Hi all, If i run a model in qdec that inludes 1 discrete and 1 continuous factor, does the output for the group contrast covary for the continuous variable? For example, if I want to compare two groups, and include group as my discrete factor and age as a continuous factor, will the output for the group contrast (Does the average thickness differ between grp1 and grp2?) covary for age? I've notice that running it without continuous factors leads to different results, so I just wanted to confirm this is the case. Also, just wanted to check that group contrasts are run as level_1 - level_2, so that positive values (i.e., red-yellow) indicate level_1 > level_2. Thanks for your help, Alex

white matter problem
by Matt Colvin 30 Oct '07

30 Oct '07

Dear Freesurfer gurus, Hello, my name is Matt Colvin, with the Conte Center at Washington University in St. Louis. I came across a problem with a particular brain where the wm and pial lines cut out a chunk of white and grey matter. I have not come across a problem quite like this one so I was wondering if anybody had a suggestion as to how to fix it? I believe it is in the insula of the left hemi of this brain, though I am not certain (the region gets labeled as "unknown" in the parcellation). I have attached two screen caps which show the problem area. Thanks for any help anyone could offer. --Matt Colvin

old Mac ver.

Hi, I have a radiologist that wants to do some freesurfer work, visualizing subcortical parcelations and orig and T1 volumes. The volume processing was done with freesurfer-v3.0. Can I install the current freesurfer-Darwin-tiger-stable-pub-v4.0.1-full.dmg and have it correctly visualize the volumetric parcellation data generated with 3.0 or do I need to get the PowerPC 3.0 version from you ( if possible ). thanks Greg.
