The file that I have downloaded is named "unKnow" and it is of 7.6 MB. I have placed it in $FREESURFER_HOME/bin directory but the error persist. Anastasia, I apologize. Please, have patience with me :-) but .. when I search for "mris_resample" in mail list I did not found any indication. I found my previous mail and first Zeke response.

field of value too small, wrap-around
by Maria Kharitonova 06 Jun '13

06 Jun '13

Hello, We have a relatively small FOV in our study because we mostly scan kids. Sometimes we scan adults with the same protocol, though, and after looking through the adults' reconned brains, I've noticed wrap-around on some brains. For one subject it's particularly bad; it affects aparc labels, where the very back of the brain gets labeled as orbitofrontal cortex. Is there a way to remedy this (other than increasing the FOV for subsequent subjects)? E.g. manually relabeling the affected regions? I'm pretty new to FreeSurfer, so I apologize in advance if this questions is naive. Thanks!

Hi Anastasia, I have resolved the previous problem by writing configuration file with sudo nano in command line. Now I'm running trac-all -prep but I have this error: writing registered surface to /Applications/freesurfer/subjects/subject_prova/Diff03/surf/rh.cvs.tocvs_avg35.sphere.reg...expanding nbhd size to 1mris_resample: Command not found.

Re: [Freesurfer] Still confused by group analysis..

Thanks Doug, > So if I want to use the study-specific "average" subject surface with >> mri_surf2surf, rather than the generic "fsaverage" one, how can this be >> done given that the required ls.white file only exists in the latter but >> not in the former? Can I just rename (or duplicate) ls.white into >> ls.white_avg? >> >> You can copy it or create a symbolic link. So it is OK to copy the required lh.white file from the generic average subject "fsaverage" and apply mri_surf2surf upon the study-specific average subject ("average")? It still seems to me that "average" should have its own (different) lh.white... > >> Shouldn't the input to mri_glmfit be the output of mri_surf2surf? In the >> group tutorial, the former is "lh.gender_age.thickness.10.**mgh" while >> the latter is "lh.gender_age.thickness.10B.**mgh".

But if all these commands transform the same file (output of mris_preproc becomes input of mri_surf2surf, which then feeds into mri_glmfit), then why is it still necessary to keep intact the original lh.gender_age.thickness.10.mgh, when all you need for the group analysis is the mri_surf2surf'd version? > >> Assuming the label files (corresponding to my ROI, and extracted from the >> Destrieux atlas) are different for each subject, and given mri_glmfit is >> called just once, for all subjects, which label file (corresponding to what >> subject) should I point it to? >> >> You need to create the label in the average subject. There is a > Destrieux atlas there. Again, by "average subject" do you mean here the generic one (fsaverage) or the study-specific one (average)? Should the former be used at any point of a group analysis, if the latter exists?

Re: [Freesurfer] Freesurfer Digest, Vol 112, Issue 17
by McMains, Stephanie 06 Jun '13

Here is the original thread (to at least most of it). Maybe I am just an idiot, but I cant' figure out how to easily reply from the web to an entire thread, and pulling it out of the digests I get is a pain!! They wanted to take an ROI from SPM and put it into free surfer to extract cortical thickness. I thought going through fsaverage was a good way to do this. But as I said, looking at the surface, I have some concerns. I am more confused by when you tell them to run the MNI template through recon-all to get a surface, because I thought fsaverage was a kind of MNI space that has already been run through? Thanks, Stephanie what space is your VBM map in? doug On 06/05/2013 11:06 AM, Ozranov-Palchik, Ola wrote: > Hi Doug, > > Thank you for your response!

The tal coordinate is notoriously inaccurate in cortex. You are verylikely to totally miss the area you are looking for.

The feasibility of this procedure
by 淼 06 Jun '13

06 Jun '13

Dear FS, I want to do an analysis with freesurfer but this is relatively complicated. I would like to know whether this is doable by freesurfer. I first want to create a custom template based on my subjects and I have seen the SurfaceRegAndTemplate page and this should be the place where I should start. Then I should use mris_register to register all my subjects to the new template. Then I want to export volume data of each region of interest and total intracranial volume of subjects to SPSS for further analysis and I don't have a clue on how to do that yet. Do you think this is feasible? Any problems there? Thanks for any help in advance. Miao Sent from my iPhone

averaging tracts?
by Hoptman, Matthew 06 Jun '13

Hi all, Thanks for tracula , which I think is a terrific tool. Is there any way to average tracts across subjects for viewing purposes? I have in mind somehting along the line of a group average merged_avg33_mni_bbi.mgz. Thanks, Matt Matthew J. Hoptman, PhD Research Scientist V Nathan S.

Enquire about running FreeSurfer {Disarmed}
by pablo najt 06 Jun '13

Hello I have a question regarding the installation/running FreeSurfer.I have just completed the installation and got the confirmation that Free surfer was installed. Please see snapshot.However when I follow the steps for testing (https://surfer.nmr.mgh.harvard.edu/fswiki/TestingFreeSurfer) I always get "command not found". I was wondering if you would be able to help me.Thanks,Pablo

problem about file format
by huang bs 06 Jun '13

06 Jun '13

Hi All, Sorry to take up your time. My freesurfer now can not recognize the re-con files (such as the .mgz files, or .xfm files, etc). For example, I run this command to check the talairach transform: *tkregister2 --mgz --s linziyi --fstal --surf orig* The terminal then reports: *ERROR: /home/virtualuser/freesurfer/subjects/linziyi/mri/transforms/talairach.xfm does not start as 'MNI Transform File* This file *talairach.xfm* does exist. But under Xubuntu, this talairach.auto.xfm file has a different icon and appears as "executable file". That's quite strange because I did not make such change to it. These files did work when I just finished the re-con. But afer the re-con, I moved them from the freesurfer subjects folder to the shared folder (shard with XP), because the freesurfer subjects folder has a limited space. After a few days, I moved them back to the subjects folder for doing the statistical analysis, and then I have such problem. Even under the shared folder, the files can not be read either. For the cases I just re-con, since they are not moved to elsewhere, everything seems OK. Have you guys had such problem before and how to fix it? Thanks! -- Best Regards, B Huang
