mri_label2label problem
by Righart, Ruthger Dr. 15 Jun '11

15 Jun '11

Dear Freesurfers, I am using mri_label2label in Fs v5.0.0 to map a label between subjects. I have some problems in that the target label shows little holes while the location of the target label seems to correspond rather well with the source label. Checking these holes backward to the source subject using the function tools/send to subject in tksurfer ... brings the saved point in the source label. I think this problem has been reported in the list before (see copy below) but unfortunately I do not find a solution that removes the holes. In my case I see this now and then both for ROIs that I drew myself in tksurfer but also pre-defined ROIs that were already there (e.g., rh.G_and_S_cingul-Mid-Ant.label). What might go wrong here? I am using --regmethod surface and trgsurf white. I wondered further how one may check how well mri_label2label worked for each subject. Is there a way to test that source and target labels have the same location in terms of for example gyri and sulci? Are there cases that mri_label2label cannot work? Thank you very much for your help, any suggestions appreciated!

Douglas N Greve Tue, 21 Sep 2010 06:47:09 -0700 what does the original label look like? Can you convert one of the predefined labels (eg, lh.V1.label) to see if the same thing happens? doug Pye, Brandon (NIH/NIMH) [F] wrote: > Hey guys, > > We are using mri_label2label to convert a label created from a cluster (using > mri_surfcluster) from an average subject to each individual subject.

mri_ca_register error
by Vanessa Lim 14 Jun '11

14 Jun '11

Hi, I am getting the same error. I did set the environment to an external drive with LOTS of space. When I run it though I did notice it repeats the subject path which is the external drive but then says actual path ~/apps/freesurfer/subjects - this doesn't have much space cause it's a virtualbox and I don't know how to make it bigger. But the error below seems to be pointing to the right directory /home/...Desktop etc. > > GCAMwrite(transforms/talairach.m3z): gzip encountered error. > writing output transformation to transforms/talairach.m3z... > mri_ca_register: GCAMwrite(transforms/talairach.m3z) failed > ERROR: mri_ca_register with non-zero status 252 > but continuing despite the error > #-------------------------------------- > #@# CA Reg Inv Thu May 26 12:42:11 EDT 2011 > /home/virtualuser/Desktop/freeSurfer/CG2/mri > > mri_ca_register -invert-and-save transforms/talairach.m3z > > Loading, Inverting, Saving, Exiting ... > Reading transforms/talairach.m3z > ERROR: cannot find or read transforms/talairach.m3z > ERROR: mri_ca_register with non-zero status 0 > Linux FreeSurfer 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux > > Cheers, > Vanessa

error in *recon-all -all -s* and *qdec*
by Sophy Zhu 14 Jun '11

14 Jun '11

Hello, Freesurfers, When I use *recon-all -all -s ...* there exists the error *mris_volmask.bin: error while loading shared libraries: /usr/local/freesurfer//lib/vtk/lib/vtk-5.2/libvtkRendering.so.5.2: cannot restore segment prot after reloc: Permission denied* Would you please tell me how to solve it? Another problem is that I cannot use the *qdec*, does this error come from my installation of freesurfer? Thanks a lot Sophy

that's weird. I'm not sure what to do. The log says that it is creating T1.mgz and not t1.mgz.

Adding a new measure to the design tab
by Jeanette Berberich 14 Jun '11

14 Jun '11

Hi, So I'm trying to add new measures, after having run recon-all -qcache, to my design tab drop-down menu and it doesn't seem to be working. I was a little confused about the .Qdecrc file. I put a file named qdec.Qdecrc file inside my $SUBJECTS_DIR/qdec/ and i also have a qdec.fsgd file in the same place. I'm not sure what else to do to get my new measurements to show up. Thank you so much, Jeanette

Re: [Freesurfer] Resampling from MNI 152 to MNI 305 - Problem with orientation
by Seán Froudist Walsh 14 Jun '11

14 Jun '11

Hi Balaji, fslswapdim (a command line program which comes as part of fsl) should solve your orientation problems. If you have fsl installed (which you should do!) then typing fslswapdim input_volume_name -x output_volume_name into the terminal should swap RAS to LAS and vice versa. Or you can just type in fslswapdim into the terminal to get help. Best of luck! Sean

Hi, I'm interested in pulling out segmentation stats on the Pulvinar. I noticed that Pulvinar is listed in the FreeSurferColorLUT.txt but isn't in the aseg.stats. Is there a way to get segmentation information for the Pulvinar? best, Peter
