Re: [Freesurfer] tips on the gtmseg.mgz check
by Ferraro, Pilar 31 Mar '20

31 Mar '20

External Email - Use Caution Dear Freesurfer experts, I’m performing an analysis using PETSurfer and, after processing all the T1 images with the Freesurfer analysis, I’m now creating the segmentation for the GTM. I’ve run the gtmseg —s command on a first subject. I was surprised though, cause I’ve read the process should have taken about an hour or two, but it actually took only 25 minutes, so, even if at the end of the process it was reported “gtmseg done”, I’ve checked the resulting gtmseg.mgz image using the command: tkmeditfv subject/ nu.mgz -seg gtmseg.mgz gtmseg.ctab -opacity 1 And this is how it looked like: [cid:A7433273-09FF-4594-A618-91107110F8B0] My question is, is there something specific I should check in this image to be sure everything has been done correctly? Sorry, I’m new to this type of analysis, so I’d rather be sure about everything before further proceeding.

I have ran the recon-all command which finished without errors. However, the white/grey matter boundaries are significantly misaligned with the subjects T1 (images attached). Below are the steps I have taken to reach this point in the analysis: 1. Run fsl_anat to get a bias corrected T1 and T1_biascor_brain. 2. Ran Feat ? Distortion correction of the EPI ? Motion correction ? No smoothing ? Highpass filter ? No registration to whole brain ? Register to T1_biascorr_brain ? Register to standard space 3. Ran recon-all on T1_biascorr 4. Convert T1/T1_brain/orig(001) from mgz to nii 5. Check registration (using the SurfaceProjection command from the SamSrf package) which leads to the attached images named S1 and S1.

But for the .lta files, there seems to be no detailed explanation regarding it. Can anyone point out to me where can I find the detail explanation of the file? And, what's the relationship between .lta and .dat file? Also, .lta files seem to cause some compatibility issues. For example, if I use the tkregister2 utility to make some changes to the registration file of type .lta (generated by bbregister), like below tkregister2 --mov $someSeries --reg $SUBJECTS_DIR/$subjectid/mri/transforms/FLAIR.auto.lta --surf pial and save it from the GUI, then many errors occur in the console window, like below: ...... MatrixAsciiReadFrom: could not scanf parms ERROR: TransformLTA2RegDat(): type = 2011264000, must be 1 or 0 or 14 Segmentation fault (core dumped) Actually that is because the registration file has been saved in the format of .dat, although the file extension is still .lta, and the tkregister2 program finally cracks when reading the newly saved .lta file.

External Email - Use Caution Hello Mina, I see from https://www.centosblog.com/centos-eol-dates/ that CentOS 6 will no longer be updated as of 11/2020, and similarly for CentOS 7 in 6/2024.  It looks like CentOS 8 was released around September of 2019.   While we do not currently build/test on CentOS8, I am sure it will eventually be supported.   Given some users will continue to use CentOS 6 even after 11/2020 and that many people have been running the freesurfer 6 release on CentOS6, then even the upcoming freesurfer 7 release is targeting CentOS6, CentOS7 and Ubuntu linux (as well as Mac OS). There is also currently an Ubuntu 18 VM with freesurfer 6 and the beta release of freesurfer 7 pre-installed which you can find here, https://surfer.nmr.mgh.harvard.edu/fswiki/VM_67 - R..

The FreeSurfer v7.0.0 Dev and the Matlab2014b (Run Time Version) has also been installed. But are getting errors. E.g., "...

It looks like a similar problem existed in 2018 (though I cannot find a fix). https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg56815.html Any help would be greatly appreciated. Thanks in advance! Regards, Chester

mri_vol2vol

External Email - Use Caution Dear Freesurfer experts, In order to transform a segmentation mask (example.mgz) from native so standard MNI space I ran: mri_vol2vol --talres 1 --interp nearest --mov example.mgz --s 001.mgz --targ $FREESURFER_HOME/subjects/fsaverage/mri/orig.mgz --regheader --o example.mni305.mgz the output example.mni305.mgz did somehow transform to a different space as you can see in Screenshot orig where the native mask is white and the transformed mask is red. However, the masks seems to be in a completely different brain region in the native MNI space (Screenshot MNI). But the point of transforming my segmentation mask is that the segmented mask should be in the same brain region but just transformed to the standard space. How can I correct this? Many thanks for the support! /Ben -- ____________________________________ Benjamin Victor Ineichen, MD PhD Karolinska Institutet Center for Molecular Medicine Stockholm, Sweden ineichen(a)protonmail.ch +41 76 391 04 01 Dr. med. et Dr. rer. nat.

mri_vol2surf projections for subcortical structures
by Niels Janssen . 29 Mar '20

29 Mar '20

External Email - Use Caution Dear list I am working on a project in which we want to extract hippocampal surfaces using mri_tessellate and then overlay these surfaces with fmri activations from nifti files using mri_vol2surf. However, I am unclear whether mri_vol2surf can be used for surfaces derived from subcortical structures like the hippocampus. Crucially, these structures are unlike the cortex in that they have a closed shape and therefore the projection of activation to a surface may be more complex than in the case of cortex (which surface normal should one take?). So I guess my question is whether mri_vol2surf works for these kinds of surfaces or whether some other approach should be used. Thanks!
