Re: [Freesurfer] error loading datatable in qdec

As far as I can see the levels file should have Male Female <newline> as its contents. Check if the <category> you have used in the qdec.table.dat file, is it the with same name? E.g. if you have the field as SEX, then the <category.levels> file should be called <SEX.levels> Hth, Shantanu PS: could you CC freesurfer list as well?

Problem importing DICOM
by Memarian, Negar 19 Nov '12

Hello, I'm using Freesurfer on Windows 7 using VirtualBox. I want to import DICOM files based on the "FreeSurfer Troubleshooting Reconstruction Work Flow", but I'm facing problems. This is what I have done: 1. Tried to use the source command like this: source C:\FreeSurfer_data\SetUpFreeSurfer.csh But I got this error: C:FreeSurfer_dataSetUpFreeSurfer.csh" No such file or directory 2. Tried to change directory to my subjects directory like t this: cd C:\FreeSurfer_data But got this error: C:FreeSurfer_data" No such file or directory 3. Tried importing one subject like this: recon-all -i C:\FreeSurfer_data\DICOM2 -subjid subj2 However I get this error: ERROR: cannot find C:FreeSurfer_dataDICOM2 Linux FreeSurfer 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i 686 GNU/Linux recon-all -s exited with ERRORS at Mon Nov 19 14:50:58 EST 2012 I tried the above commands with / (slash) instead of back slash but still got similar errors.

exporting aseg.stats values

Hi FreeSurfer users and developers, I'm trying to export aseg.stats values for a preliminary analysis. I would like to export them to an excel spreadsheet.

shared installation of freesurfer
by Lilley, John F. 19 Nov '12

19 Nov '12

Hi, We have setup a central install of free surfer but are having some difficulty with the license management aspect. Is there a way to run a single install instance yet have each user provide individual license location variables out side of $FREESURFER_HOME? (~/.license etc.) If not, would registering a single freesurfer license for the cluster in question be acceptable under the license conditions? If there's a better place for this email please let me know. Thanks, John

Subgroup analysis
by Mahinda Yogarajah 19 Nov '12

19 Nov '12

Dear Experts, I have a two groups - a control group and patient group. The patient group can also be divided into 4 subgroups (but not control gp). Both groups are evenly split between male and female. So far I have compared the patient and control groups as a whole (age and icv as continuous/nuisance variables) but now i want to compare each of the subgroups to controls. I have tried doing this in qdec very crudely by running 4 analyses in qdec where I exclude all the subgroup cases execpt for those belonging to the subgroup I am looking at. My questions are 1) Is this valid (I would correct for the multiple tests) ? How does qdec cope with exclusions given that variables (age) have been demeaned across a whole group. 2) Is there a better way of comparing my subgroups to controls ? Thanks. Mahinda

Re: [Freesurfer] fieldsign-sess problem in retinotopy
by Zhou, Wei 19 Nov '12

19 Nov '12

Hi Doug, It seems the previous fieldsign-sess problem is due to that I stored data on one server while freesurfer is on the other server. But when I put the data and freesurfer on the same server and run the retinotopy analysis again, it reported fail msg for "selxavg3-ses" : -- ntptot = 80, nX = 27, DOF = 53 Saving X matrix to /media/local_home/zhouw4/testf/retinotopy/SUBJ01/bold/rtopy.self.lh/Xtmp.mat Error using svd Input to SVD must not contain NaN or Inf. Error in cond (line 39) s = svd(A); Error in fast_selxavg3 (line 254) XCond = cond(XtX); --- I checked Xtmp.mat. There is NaN in Xn and XtX. My rtopy par is: eccen and pos. Would you please give me some idea about this error?

Re: [Freesurfer] interpretation of vertexwise thickness, area, volume analysis
by Mahinda Yogarajah 19 Nov '12

19 Nov '12

Hi, Thanks for the reply. I am using the new script and I should correct myself in that my significant volume changes do seem to correspond (although they are not completely identical) to areas where there are significant area differences (I see no significant thickness differences between my groups) - using this kind of vertex wide analysis how does one interpret (biologically) these area differences. One other quick question regarding monte Carlo correction in qdec - when I use more stringent p thresholds my significant clusters get smaller as one might expect but I also see a completely new, small cluster in the Cingulum which is not seen at less stringent thresholds - is this kind of behaviour ok ? Thanks. Mahinda

mismatch of parcellation and pial surface
by 嘉逸劉 19 Nov '12

19 Nov '12

Dear Freesurfer experts, I met a problem as shown in the appended figuer. You can see that in the insula, the pial surface abnormally curves in but the parcellation seems recognize the boundary of gray and white matter quite well. The tutorial tells us how to correct pial problem which generally incorporates dural as gray matter. However, in my case, the pial is too conservative in that region, ignores the gray matter, and nearly overlaps with white matter boundary. I cannot get help from the tutorial/manual. Could you please guide me how to correct this problem? Thanks in advance, JoJo
