mri_convert defaults to trilinear interpolation if "--like" option is used, regardless of "-rt nearest"
by Harris Hoke 11 Apr '17

11 Apr '17

I’m currently running freesurfer 6.0.0, and I’ve run into the same problem described in this thread on the archives <http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg43697.html> . Does anyone know if a fix exists? I'm trying to move binary parcel files from the SPM default MNI152 space to Freesurfer cvs_avg35_MNI152 space. ~Harris

recon-all -parallel osx sierra
by jasi3k 11 Apr '17

Dear all, I am using Freesurfer 6.0 to run recon-all on 0.8 isotropic data. Whenever I use the parallel flag I get this error. dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address Same subject without the parallel flag runs smoothly but of course takes much longer. I have seen a similar problem on the list and the suggestion was to make a clean install of Freesurfer 6.0, which I did but unfortunately it didn’t help. Any suggestions will be appreciated. Best, Jan

segmentation help
by Dilip Puri 11 Apr '17

11 Apr '17

Hi all, I've 200 analyze7.5 format images(OASIS Dataset) and I want to segment HippoCampus. My input file xyz.img and output file will be like xyz_seg.img which contains only hippocampus image it like Grond Truth image for my original input image. Here is sample files including original and segmented mask link <https://drive.google.com/open?id=0B6rH1c6LupG_b3I4WUJ1RWZCbnM>. Even I am very new to FREESURFER so I don't know the procedure to reconstruct the images. Kindly help me.

Difference in Recon-All Output Between Freesurfer Versions?
by Taylor, Johnmark 10 Apr '17

10 Apr '17

Hello, Recently, I re-ran recon-all with Freesurfer version 5 on some subjects whose surfaces had previously been reconstructed with Freesurfer version 4. As a result, it appears that their surface reconstructions have subtly changed, such that the labels that were specified in the old reconstruction are all messed up in the new reconstruction (since the surfaces that they were once associated with have changed). Did recon-all change between Freesurfer versions, and if so, is there a way to go back to the old algorithm short of simply switching back to Freesurfer version 4? It is possible that I have accidentally changed something else and that's why the surface files are different, but I wanted to see if there were any changes in the reconstruction algorithm between versions that might have caused this. Thank you very much, JohnMark Taylor

Re: [Freesurfer] -autorecon2-wm: Inconsistency between recon-all code and documentation
by Antonin Skoch 10 Apr '17

10 Apr '17

Dear Doug, do you think that it is necessary/useful to rerun -normalization2 -maskbfs -segmentation steps after wm.mgz have been edited (that is what the -autorecon2-wm is used for I suppose)? The wm.mgz is not used in this steps as far as I can tell. In contrast, it seems to me that the documentation is more close to the optimum (the three steps: normalization, mask and segmentation steps are run only when it is needed - in -autorecon2-cp, not in -autorecon2-wm). Antonin I think the stages in the command line help are out of date On 04/08/2017 05:58 PM, Antonin Skoch wrote: > Dear experts, > > I noticed inconsistency between recon-all -help and actual code of > recon-all in -autorecon2-wm option. > According to the recon-all --help the -autorecon2-wm processes stages > 15-23 (fill through make white surfaces) and -autorecon2-cp processes > stages 12-23 (normalization2 throuhgh make white surfaces).

calculating geodesic distances between vertices
by Burke Rosen 10 Apr '17

10 Apr '17

I am interested in finding the distance between two vertices along the cortical surface. So far I have used two methods: (1) Compute the shortest path with a variant of Dijkstra's algorithm on the white surface. (2) Compute the great circle distance on the sphere surface. (as done by Risk et.al. 2016 Neuroimage) Method (1) is slow and will tend to overestimate distances as the path only goes along mesh edges. Method (2) is very fast and gives a true geodesic but gives a scaled result because the radius of sphere surface is arbitrary; also this method is subject to distortions introduced by the inflation algorithm. My current strategy is to perform a linear regression between the triangle face areas of the sphere and white surfaces. And then apply the coefficients to the sphere surface diameter before calculating geodesic distances. This yields a distance matrix with a similar pattern to the Method (1) at about 62% scale. That scale seems like it might be reasonable. However, the regression only explains ~58% of the variance. My hunch is that the rest is due to inflation distortions. Is there a better way of scaling the sphere surface? Or a way to inflate in such a way that inter-vertex distances are preserved? Or, more generally, what is a good method of computing geodesic distances on freesurfer surfaces. Thank you, Burke Rosen
