FreeSurfer results for Allen Brain Atlas donors?
by Keith Jamison 29 Apr '21

29 Apr '21

External Email - Use Caution I just came across this page that describes freesurfer outputs for the 6 Allen Brain Atlas donors: https://secure-web.cisco.com/1tWRubEIGq1Vc2e5IRFbcyZbKrPn8IuChYlWsqD8Clzjen… There's a recent note saying the data has been moved to a sharepoint server. Access to that server appears to be restricted. Is that data still publicly available somewhere? Thanks! -Keith Jamison

External Email - Use Caution Dear Supportteam, I have a short question concerning the data produced by mris_anatomical_stats. The description on the anatomical structures is really short so I just wanted to ask if the precentral stats are for the precentral gyrus?

Freeview slow on CentOS 8 Stream
by Torkil Svensgaard 27 Apr '21

27 Apr '21

External Email - Use Caution Hi We have an older Ubuntu 16.04 HPC installation on which Freeview runs just fine. We also have a brand new CentOS 8 Stream HPC installation with much better hardware on which Freeview slows to a crawl after a bit of use. There's no error as such, it just slows to the point of being unusable. Any suggestions on how to fix it, or pinpoint the cause? Thanks, Torkil

Freeview issues with surfaces
by Pål Gunnar Larsson 26 Apr '21

26 Apr '21

External Email - Use Caution I have made a new install of everything, now running Ubuntu 20.04 with Virtualbox 6.0 and Freesurfer 7.1. Freesurfer crashes with : "nquads=10158084, nvertices=529 terminate called after throwing an instance of 'int' Aborted (core dumped)" If I try to open surface lh.area or lh.thickness. Others like lh.pial and lh.inflated works nicely. I have tried this with one of "my" patients and bert with same result. Suggestions? Pål Pål G. Larsson M.D., PhD. not sensitive

Parcellation Error Pre-Post Central Gyrus R but not L Hemisphere
by Fraser Smith 26 Apr '21

26 Apr '21

External Email - Use Caution Hi there I have a clear parcellation error with one participant who does look to have an atypical structure around the right post-central gyrus (looks split in two). Both the pre and post central gyri are shifted significantly backwards – but only for the right not the left hemisphere. I see this has been mentioned before in the archives – but I have been unable to find a fix for this. Could you provide any tips on what to try? I am using v6.0.0. Best wishes Fraser Smith

External Email - Use Caution Hi, after the transformation of the Choi's striatal 2012 to the individual subject, I would like to do the segmentation + the striatum parcellation_Choi2012. How I can do that in order to have in the end the aseg + aparc.mgz file in order to have the volume of this ROI.

T2 lesion editing
by AJ 26 Apr '21

26 Apr '21

External Email - Use Caution Hi, Once SAMSEG has finished segmenting T2 lesions, other than trying different --threshold flags, any way to manually modify them? Can --eTIV be added to SAMSEG? In Samseg, can brainstem be segmented into parts, such as medulla, pons, mid brain like through recon all? Can corpus callosum be segmented separately in Samseg? Sorry for all the questions. Many thanks.

glm_fit Contrast
by Boa Sorte Silva, Narlon 26 Apr '21

26 Apr '21

External Email - Use Caution Dear FS experts, Hope this finds you well. I would like to check whether the following the correct approach for my models in glm_fit. I am testing whether gait speed is associated with cortical thickness, adjusting for 4 covariates (sex, age, bmi, and mmse). I have sex as a factor (two levels: male or female), age, bmi, and mmse are continuous variables. Thus, the FSGD file is ordered as: subj_id sex gait age bmi mmse In the models, I am using DOSS with the following contrast: [+0 +0 +1 +0 +0 +0] I would appreciate your kind input as to whether the above design and contrast is the proper way to test my research question. Thank you very much for your help.
