External Email - Use Caution It looks like your terminal/character settings are messed up in the current terminal session.  That can happen from trying to look at a raw binary or image file in the terminal window or running something that outputs non-standard characters to the terminal (stdout).  I would open a new terminal window, source the freesurfer setup script, and try to identify if something you run corrupts the display of text in the new terminal window. - R.

dt_recon eddy correction fail and freeview errors
by Ward Deferm 26 Oct '22

26 Oct '22

External Email - Use Caution Dear Freesurfer Developers, I am trying to perform the dt_recon command for a single participant of my dataset. The original data comes from a philips scanner and was in the PAR/REC format. I converted these files to nifti’s using dcm2niix. This seemed to have worked as I got my nifti files and .bval and .bvec. However, when I run the dt_recon command it does not give me a hard error, but the output is not how it should be. Instead of taking 1-2 hours to complete the command, the command is done in about 3 minutes and I’m doubting if the eddy corrections are actually performed (fsl seems to be installed properly and is recognized when sourcing freesurfer. When trying to view the output with freeview I get 2 outcomes. Sometimes all of the file's work but there is no eddy correction performed and the FA volume is spread all over the brain when looking at this volume using freeview. But other times certain volumes either refuse to load or come up as a blank rectangle. In the freeview command line I then get the error: WARNING: 37103 NaNs found in volume /home/ward/freesurfer/subjects/testdtrecon/dti/ra.nii.gz In the attached files you can find the dt_recon log file. As for version and operating system I am running: 1) freesurfer-linux-ubuntu22_x86_64-7.3.2-20220804-6354275 2)Ubuntu 22.04.1 LTS Kind regards, Ward Deferm

LGI and further errors
by FMU 26 Oct '22

26 Oct '22

External Email - Use Caution Hi everyone, I’m running a brain surface ROI analysis using data from the HCP. I need to draw those ROIs to be in annot files format so I can use them for further analysis to calculate sulcal depth (https://secure-web.cisco.com/1BjH9by7q1Ifs37LZrnji4YAMniNy1LLAc_r-1HVnNxAiv… <https://secure-web.cisco.com/1BjH9by7q1Ifs37LZrnji4YAMniNy1LLAc_r-1HVnNxAiv…>). I draw all my sample (n=40), and to proceed to the next step, I need to measure the LGI in each subject. In some samples, I faced a similar error to the one mentioned in this thread: https://secure-web.cisco.com/13Nu69ZC35kQC9epIBWd44yarBEBej9ZnSy-C1Z9Zpg_sr… <https://secure-web.cisco.com/13Nu69ZC35kQC9epIBWd44yarBEBej9ZnSy-C1Z9Zpg_sr…> I tried to run the recon-all lgi again the error remained the same. I did as recommended to run the recon-all -s sub -hemi ?h -autorecon2 & 3 The new surfaces were there, and the recon-all lgi worked fine. However, my annot files were not OK with new surfaces, and I don’t know what is exactly the problem, but I will attach an image showing how the labels looked in the original HCP data brain surface and how they look after the recon-all -s sub -hemi ?h -autorecon2 & 3. I re-downloaded the original surfaces from the HCP database, and it returned to its normal display. I hope someone can help me to solve the problem, and I appreciate it. Mudathir

External Email - Use Caution Dear freesurfer, Are there any additional resources on how to make cuts? I have found this https://secure-web.cisco.com/18_liDyv7h8S0t-GuSrqbS0mexl0ornQBxqLR6v5JlLJUx… but it isn't enough for the project I am doing. I want to flatten the whole surface but I may need to change where I am cutting from patient to patient. How do you know how big the hole should be? and how many relaxation cuts should you make? How long should they be? If you have any more guidance on how to cut to minimise distortion, please let me know! Also when I perform the mris_flatten function using my patch, my terminal gives me a % near the end saying "41% total metric distortion". Can you confirm that this value is the total metric distortion from an inflated surface to a flatmap surface using my chosen patch? Many thanks, Sarah Lavelle Trinity College Dublin
