External Email - Use Caution Yes, you can disable the gatekeeper security software and allow software to be installed anywhere.  This may not be the best choice for everyone if you prefer to have this security (or do not have sudo privs).   Anyway, we will endeavor to not require this. - R.

Hippocampal subfields: exporting results
by Steve Petersen 11 Dec '19

11 Dec '19

External Email - Use Caution Dear Freesurfer experts, I used the freesurfer dev version to estimate hippocampal subfields using mode B (additional scan). All have worked fine although when I tried to export the results I can not find the txt file created This is the output rmnlab1:~ neucoga$ quantifyHippocampalSubfields.sh HIPOAMYG HipoAmyg_results.txt /Applications/freesurfer/subjects/4001T1 Gathering results from subjects in: /Applications/freesurfer/subjects/4001T1 Using the suffix name: HIPOAMYG And writing them to: HipoAmyg_results.txt Where is saved the HipoAmyg_results.txt file?? I have searched it and I can't find it... Excuse me for this basic question. Thanks in advance. Best regards,

External Email - Use Caution Hello CM, We are looking at how Freesurfer can work with the new security and file system changes added in Catalina (Mac OS 10.15).  I am not aware of an issue if Freesurfer had been installed on a machine running an older version of Mac OS, e.g., Mojave (Mac OS 10.14), that was subsequently upgraded to run Mac OS 10.15.  But we still need to testing - including new Apple hardware that comes with Catalina installed out of the box.  Like other software vendors, at this time we do not recommend upgrading to Catalina if you want to continue to run existing (Freesurfer) software releases on Mac OS. - R.

tkregisterfv problems
by Vicky Yang 10 Dec '19

10 Dec '19

External Email - Use Caution Dear Freesurfer experts, I am using bbregister to register my functional template image into T1 image. The bbregister is running fine. But when I tried to view registration using tkregisterfv, the window opened and closed quickly with an error message: Warning: Transformation can only apply to volumes for now. If your data includes ROI/Surface/Way Points, please do not use this feature yet. INFO: This REGISTER_DAT transform is valid only for volumes between COR types with c_(r,a,s) = 0. LTAchangeType: src geometry must be valid terminate called after throwing an instance of 'int' Abort (core dumped). My command: bbregister --s subj_ID --mov template.nii --reg bbr_template_T1.reg --bold --init-fsl tkregisterfv --mov template.nii --reg bbr_template_T1.reg --surfs Can anyone help me with this? Thank you so much! VY

Using pre-segmented results
by Jordi Huguet 10 Dec '19

10 Dec '19

External Email - Use Caution Hi there, I wonder if its somehow possible to feed FreeSurfer's recon-all with pre-existing segmented maps (based on prior segmentation procedure e.g. SPM or ANTs) to "improve" FreeSurfer results. For some images I am working with the FreeSurfer's WM segmentation output is not optimal so I am looking for alternatives to improve the final results on such specific cases without requiring any manual intervention. Any comments, examples or shared reflections on this regard are kindly welcome. Thanks in advance, Jordi Huguet

Is subcortical segmentation reliable when cortical segmentation fails?
by Fredrik 10 Dec '19

10 Dec '19

External Email - Use Caution Hi FreeSurfer experts, In our data, we have a sample of older people with brain athrophy. This influences the cortical segmentation, where it can take into consideratin the skull, and/or leave out grey matter. My question regards the subcortical segmentation in such cases: Is it reliable to use the subcortical segmentation when the cortical segmentation clearly fails? Thanks, Fredrik Magnussen

intensity map
by a Chinese reader 10 Dec '19

10 Dec '19

External Email - Use Caution Dear Freesurfer experts,I have some questions about intensity map: 1. If I would like to get intensity maps of WM, which were created at 1 mm below the white surface, and the GM were taken at half of the thickness of the cortex. which commands I can use. 2. How to use the command line to get the Grey-matter tissue intensity at 10% up to 60% of the distance from the white matter to the pial surface. 3. Then, how to get the WM/GM intensity maps use the above values. Best regards, Zhang Xia
