External Email - Use Caution Dear FreeSurfer team I have been trying to run trac-all & keep get the error " too many ('s must specify as many DWI dicoms as subjects" There is no mismatch between my subjects list (the number and IDs) and dcmlist.

userid login as "developer" - VM_67_win {Disarmed}

External Email - Use Caution Dear all, I am trying to install Freesurfer on my Windows10 with a VM following these instructions: https://secure-web.cisco.com/1q0U-_mEzDjDxzeEdksNy6TWmfK6OyrdBwiQEuhnVHPLVU… After the creation of the VM with the cloned VM *Ubuntu_710_clone_2.7z,* I am stuck at the login window where I should login with a password for 'developer'. What is this password? The instructions quoted below, refer to a README file, but I cannot get into the desktop of the ubuntu because it I don't have a password. "*This VM contains both the freesurfer 6.0.0 release, the 7.0.0 beta 1 release, and a copy of the tutorial data used in the freesurfer courses from 2019. Please **see the README* files for more details in the home directory for the userid login as "developer". However, it does not contain a license.txt** file needed to run some commands*. " kind regards, Amice Maries

Re: [Freesurfer] Computing thickness from woT2.pial surfaces

External Email - Use Caution Hi, Bruce, in the meantime, I found the old thread https://secure-web.cisco.com/10LHEZSoeNL-wnQ2e6UBEnyfB6PA04qM13lFZXbRypPzlX… which suggests to set -N 20 parameter to mris_thickness to make thickness computation consistent to mris_make_surfaces. Indeed, the values are now consistent, with exception of several thousands of vertices mainly around medial wall. Is here any other option missing, which makes mris_thickness computed values of thickness fully consistent to mris_make_surfaces? Thank you in advance, Antonin Hi, Bruce, thank you for the instructions! I ran mris_thickness on one example subject to test the procedure. However, inspecting the values of created thickness file, I encountered problem. In many locations, the values of thickness file differ from the values of thickness file created in recon-all -T2pial. Even when the input files used for thickness measurement are (should) be the same. (I double-checked my input surfaces, when I use woT2.pial surface, the thickness values are different everywhere). Attached see the binarized difference of these thickness files with the cursor, where difference is zero (red spots) and where is non-zero (transparent). Could you please clarify, where could be the problem? Does not the thickness computation in mris_make_surfaces use different options? Could it be the reason, that I am operating with data processed by longitudinal stream? (I don't think so...). This inconsistence makes me puzzled. Regards, Antonin Hi Antonín You can specify what surfaces to use in mris_thickness:mris_thickness -pial <path to pial surface> -white <path to white surface> … cheers Bruce From: freesurfer-boun...(a)nmr.mgh.harvard.edu <freesurfer-boun...(a)nmr.mgh.harvard.edu> On Behalf Of Antonín Škoch Sent: Wednesday, December 9, 2020 6:16 AM To: freesurfer(a)nmr.mgh.harvard.edu Subject: [Freesurfer] Computing thickness from woT2.pial surfaces External Email - Use Caution Dear experts, I have processed my data with -T2pial option.

MP2RAGE pial surface error
by Elisa Rehbein 09 Dec '20

09 Dec '20

External Email - Use Caution Dear Freesurfer experts, we are currently running recon-all for our MP2RAGE images, using Freesurfer 7. However, when trying to edit pial surface errors and re-running (recon-all -autorecon-pial -subjid) it does not adjust the surface for some participants. For denoising the salt and pepper noise in the background we used the script provided by (Marcques et al. 2010). We are very confused as to why this may be happening for some subjects, as the background noise seems to be removed equally for all subjects. Do you maybe have suggestions for us how to solve this problem? Many thanks in advance! Kind regards, Elisa

convert to native space
by Wei Shao 08 Dec '20

08 Dec '20

External Email - Use Caution Hello, Freesurfer team This is Wei Shao, I was trying to convert the freesurfer automatic segmentation of the hippocampus subfield into native space so I can compare it with the manual segmentation. Here is the command: mri_label2vol --seg lh.hippoAmygLabels-BAYXXXXX-T2.v21.CA.mgz --temp rawavg.mgz --o lh.hippo-BAYXXXXX.mgz --regheader aseg.mgz 1 Could you tell me which files I should use in terms of the temp and regheader flag. 2 the manual segmentation based on T2 image, do I need to use the same T2 image as the overlaid image when it comes to Freeview? I think the nu.mgz is T1 image, could you tell me where I can find the T2 image accordingly? 3 do you know any command that can help me to check the information of the .mgz file like the 3dinfo command? I really appreciate your help, Thanks. Best, Wei
