followup question on computing merged volumes of both hemispheres
by inbal paran 08 Aug '23

08 Aug '23

External Email - Use Caution By hand/matlab - simply to sum the volumes in each hemisphere? e.g., Rt. Caudate+ Lt. Caudate? ----- You'll have to do it by hand or maybe in matlab; you can use fast_ldtable.m to load in the tables in matlab On 8/5/2023 4:54 AM, inbal paran wrote: External Email - Use Caution Hello FreeSurfer Developers, I need to compute the volume of specific bilateral cortical and subcortical ROIs.

Re: [Freesurfer] Calling segmentThalamicNuclei.sh Issue

Bad skull strip
by DS 07 Aug '23

07 Aug '23

External Email - Use Caution Hi expert, I found an issue when I do skull stripping. I used the following command line. recon-all \ -skullstrip \ -s fs_output \ -clean-bm \ -wsthresh 100 But, I found too much brain tissue has been removed, particularly for the visual and motor cortex, please see below. Do you have any thoughts about this issue? Even though I tried wsthresh=100, it's still not working. I am not sure how I can include more brain tissues. Looking forward to your reply. Thanks. Best, Cain

mri_segstats --sbTIVin

External Email - Use Caution Dear Freesurfer developer. According to the explanation in the https://secure-web.cisco.com/1coHbpSG3RMsDJ9eWWcn4zb_ld9qaPCVetqOo5rL5vuLfQ…, it seems that the TIV volume of SAMSEG pipeline could be added to the aseg.stats with the option of mri_segstats --sbTIVin <sbtiv.stats> ... But, I can not find "--sbTIVin" option in the mri_segstats command of FreeSurfer 7.4.1 or the recent developer version. How can I add sbTIV to aseg.stats?

Question about group analysis
by inbal paran 07 Aug '23

07 Aug '23

External Email - Use Caution Hello FreeSurfer Developers, I have a question regarding group analysis: When I followed the instructions on how to build my FSGD file, it said that:"FSGD files are created automatically by qdec, but qdec is currently (12/9/08) limited to two continuous variables and two discrete variables with two levles. Is this still the case, or is it possible to include more than 2 continuous variables?

How to compute the merged volume of both hemispheres per each ROI

Errors Running tkmedit
by Edwards, Vincent 07 Aug '23

07 Aug '23

External Email - Use Caution Hello, Our lab has been using Freesurfer 5.3 for it's ongoing longitudinal study. I attempted to quality check one of our brains using tkmedit - I usually don't have any issues following our pipeline or running the tool. This time I received this message: ERROR: A segfault has occurred. This is not your fault, : but is most likely an unrecoverable error and has : made the program unstable. : : Please send the contents of the file .xdebug_tkmedit : that should be in this directory to freesurfer(a)nmr.mgh.harvard.edu : : Now exiting... : I'm not sure where the xdebug file is located - it isn't anywhere in our Freesurfer directory in the server. Where can I find this file, and how can I fix this error? I've tried trouble shooting with some solutions I've seen in the archive. We have checked permissions, I use a PC - not a mac, and I have checked the main freesurfer directories as well as the directories associated with the brain I want to check. I have also tried to open other brains in the viewer resulting in the same error message. Is there a fix for this - ideally, one that doesn't require switching Freesurfer versions? Thanks for any help you can provide! Vincent Edwards
