CC ROIs for FSL
by Hua, Jessica 26 Apr '22

26 Apr '22

External Email - Use Caution Hi FreeSurfer, The FreeSurfer atlas includes 5 corpus callosum regions. I am trying to create ROIs of those 5 regions and transfer them to FSL in .nii format to be used in DTI analyses. However, I have been unable to figure out how to put these ROIs in MNI152 space and transfer them to FSL. It was recommended that I run recon-all on the MNI template. Here is my code: recon-all -s John1 -i MNI152_T1_2mm_brain.nii -all -qcache -3T However when I try to run recon-all, I get the below message. Do you know why recon-all is not working (note: I tried this is 6.0 and 7.2)? And do you know how I can get FreeSurfer CC ROIS into MNI152 space and then convert them to FSL .nii files? #@# Curv .H and .K lh Mon Apr 25 18:54:14 PDT 2022 /Users/jessicahua/Box/John/John1/surf \n mris_curvature -w -seed 1234 lh.white.preaparc \n setting seed for random number generator to 1234 total integrated curvature = 16.045*4pi (201.629) --> -15 handles ICI = 107.1, FI = 655.1, variation=11743.051 writing Gaussian curvature to /Users/jessicahua/Box/John/John1/surf/lh.white.preaparc.K...done. writing mean curvature to /Users/jessicahua/Box/John/John1/surf/lh.white.preaparc.H...done. rm -f lh.white.H ln -s lh.white.preaparc.H lh.white.H ln: lh.white.H: Function not implemented Darwin Jessicas-MacBook-Pro-2.local 17.7.0 Darwin Kernel Version 17.7.0: Fri Oct 30 13:34:27 PDT 2020; root:xnu-4570.71.82.8~1/RELEASE_X86_64 x86_64 recon-all -s John1 exited with ERRORS at Mon Apr 25 18:54:17 PDT 2022 Thank you, Jessica

Orthographic camera in FreeView
by Anderson M. Winkler 25 Apr '22

25 Apr '22

External Email - Use Caution Hi all, Is there a way to configure the camera in the 3D viewport in FreeView to use an orthographic projection instead of perspective (which currently is the default)? Orthographic used to be the default in tksurfer. A nice feature about it is that when we zoom, the effect is the same as scaling the projection (as opposed to introducing distortions). It makes a difference when we are collating screen captures for a figure, for example. I checked the help but don't seem to find any related option (in 7.2). Thanks! All the best, Anderson

ERROR: Talairach failed!
by Fritze, Stefan 23 Apr '22

23 Apr '22

External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to compute recon-all -all -subjid XXX -qcache -3T, which works fine with most of my study participants, but for some of them I receive Talairach error (s. error message below): I've searched the list and similar errors have been reported and there is a webpage dealing with this type of error (https://secure-web.cisco.com/1RvZhQl7xG9ZOQtDHxIejsIaxH-Szi0GVQwXNg3elCyaJx…) Yet, tkregisterfv produces also an error, even when I do not set the --surf orig flag (the surf folder of these participants is empty). Running the mritotal utility from the MNI toolset produces the same error. In one participant, the problem was solved when I converted the .nifti file to .mgz and started recon-all from there. But this did not help with the other participants. Including the -notal-check flag allows recon-all to complete, yet I do not know whether the results are trustworthy. Does anyone have any thoughts on how to trouble-shoot this one? Also, Ive attached the recon-all.log in case it's of any use. 1) FreeSurfer version: freesurfer-linux-ubuntu18_x86_64-7.2.0-20210721-aa8f76b 2) Platform: 54G7T63 Kernel: 5.0.0-32-generic x86_64 bits: 64 compiler: gcc v: 7.4.0 Desktop: MATE 1.22.2 wm: marco dm: LightDM Distro: Linux Mint 19.3 Tricia base: Ubuntu 18.04 bionic 3) recon-all.log: see attached Best wishes, Stefan #@# Talairach Failure Detection Fr 11.
