Re: [Freesurfer] SPM to FreeSurfer

External Email - Use Caution Hello Rachel, SUBJECTS_DIR is preset in the terminal window to point to the example subjects already provided with the freesurfer distribution under /usr/local/freesurfer/7.2.0/subjects.  You will see subject names under that directory like “bert”.  That SUBEJCTS_DIR setting is printed out when you start a new terminal window. But it is not intended you process your own subjects there.  You don’t have permission to copy data into that location unless you use the “sudo” command. It’s preferable to set SUBJECTS_DIR to point to a subdirectory where you have permission to read and write your own subject data files such as /home/developer   If you put your data under there, then you can set SUBEJCTS_DIR to instead be, $ export SUBJECTS_DIR=/home/developer/subjects… under which you would presumably have directories referenced by subject name. To see the value of SUBEJCTS_DIR in the terminal window,$ echo $SUBJECTS_DIR To see the value of all environment variables in the terminal window,$ env | sort You can change what SUBJECTS_DIR is set to in the terminal window by editing the file /home/developer/.bashrc  I would put any export command to change SUBJECTS_DIR from the subejcts provided with freesurfer at the end of that file. - R.

External Email - Use Caution Hello Rachel, You should have just received the info for the Freesurfer Ubuntu VM. Replies to these requests are now being sent directly to the email of the requestor and are no longer copied to the Freesurfer list so as not to generate extra  list. From: Rachel Wagner <rwagne2@uwo.ca>Date: Wednesday, June 15, 2022 at 1:33 PMTo: Sennott, Liam Ricker <LSENNOTT@mgh.harvard.edu>Subject: FreeSurfer Passcode - Apologies!        External Email - Use Caution        Hello,  I hope this finds you well. My apologies for emailing you personally, I am a bit desperate - I am attempting to subscribe to the mailing list offered by the developers of FreeSurfer, as I need to email for the passcode I require to access the software. I am having trouble subscribing (for some reason I’m not getting the subscription confirming email) and thus cannot contact the listed email. I am wondering if you might be able to offer an alternative way to get in touch for the passcode I need to expand the archive (I downloaded the ubuntu VM and WinRAR)? Thanks!Rachel Wagner

recon-all -s exited with ERRORS
by Wang, Yu 14 Jun '22

14 Jun '22

External Email - Use Caution Hi, FreeSurfer Developers, I am attempting to use the recon-all to reconstruction, I successfully run this command in some subjects, but it also failed in around 1/3 of subjects. And after running the recon-all of this 1/3 subjects. It will show “mri_watershed error:GLOBAL region of the brain empty” and I already solve this with the command “recon-all -skullstrip -no-wsgcaatlas -s smwrc1NT816”. And after working with this, I tried to use the command “recon-all -autorecon2 -autorecon3 -s smwrc1NT816” and it shows the output as without given some detailed reasons: recon-all -s smwrc1NT816 exited with ERRORS at Mon Jun 13 13:54:10 CDT 2022 For more details, see the log file /Applications/freesurfer/7.2.0/subjects/smwrc1NT816/scripts/recon-all.log To report a problem, see http://secure-web.cisco.com/15s_oFH-kAftN57mqGI2bcqN1hKf4R5zXE_fPPasU_i9bJa… I’ve searched over the internet and did not find the reasons and solutions of my problems. And I will attached the recon-all.log in case it's of any use. I try to work out on two machine, and they show the same problems : 1. FreeSurfer version: freesurfer-darwin-macOS-7.2.0-20210713-aa8f76b and freesurfer-linux-ubuntu18_x86_64-7.2.0-20210721-aa8f76b 2.

mris_preproc read error
by Joanna L Eckhardt 14 Jun '22

14 Jun '22

External Email - Use Caution Dear FreeSurfer Help Team, I am working through the FreeSurfer tutorial on cannabis using Ubuntu VM on windows (FS version 7.1.1). I am on the group analysis portion of the tutorial attempting to run mris_preproc. However, I am receiving the following error upon running the script: error: No such file or directory error: mghRead(/home/developer/FreeSurfer/osg-outputs/cannabis-BL/sub-101/surf/rh.thickness.fwhm10.fsaverage.mgh, -1): read error I wonder if something has been going wrong with recon-all as I believe it is saying that there is an error with one of the outputs in sub-101? Recon-all has been running in a suspiciously short time (~5 hours), but I do not know enough about the processing steps to know what might be occurring wrong in recon-all or in trying to run mris_preproc. Please let me know if I can send you anything else to provide more information on the issue. Thank you for your time and assistance. Best wishes, Joanna

Incorporating samseg segmentation into the recon-all pipeline
by Cerri, Stefano 14 Jun '22

Hi Julian, You can use the command "samseg" with the --recon flag. See the helper function for more details (--help) Stefano External Email - Use Caution /Hello everyone,/ /We have been utilizing freesurfer for our brain morphometry and processing pipelines, and have recently tested the samseg segmentation algorithm on a clinical cohort./ /With respect to some regions, we currently prefer its results to the ones generated by the standard freesurfer segmentation algorithm. / /As SAMSEG only provides volume calculation (please correct me if I am wrong) and does not feature cortical thickness measurements,/ /I was wondering if the recon-all pipeline can be modified to utilize the samseg segmentation instead, and if so, which script(s) or chain of commands would be a good starting point to implement this./ /Looking forward to your feedback,/ /Julian / Julian McGinnis PhD Candidate TUM-Neuroimaging Center, School of Medicine, Technical University of Munich, Munich, Germany Department of Computer Science, Technical University of Munich, Munich, Germany Email:julian.mcgin...@tum.de _______________________________________________ Freesurfer mailing list Freesurfer(a)nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

External Email - Use Caution Dear Freesurfer experts,, I tried to use mri_label2vol with fill-ribbon option to covert the surface-based label of perirhinal cortex into the volume (an ROI in mgz file). However, when I typed "mri_label2vol --fill-ribbon --label lh.entorhinal_exvivo.thresh.label --o lh.entorhinal_exvivo.thresh.nii --identity" in the command line, an error popped up, saying "ERROR: Option --fill-ribbon unknown". Do you have any solution in order to make it work? Thanks, Junjie
