Re: [Freesurfer] Segmentation fault

External Email - Use Caution Hello Jon, Can you get any stack or backtrace information after the segfault occurs ?, e.g., Mac OS has the option to display the crash report with a trace.  On Linux you could run thru gdb and get a back trace.   This would help us to see where the code is exiting..

loading and rendering the Amygdala nuclei only in Freeview
by Erik O'Hanlon 19 Nov '18

19 Nov '18

External Email - Use Caution Hi FS Experts, I'm trying to make some images of my amygdala nuclei in freeview and selected my T1 as background and then loaded up lh.hippoAmygLabels-T1-HippoAMYT1andT2FLAIR.v20.FS60.FSvoxelSpace.mgz image which loads up perfectly. I selected the "show existing labels " and the freesurfer colour LUT but when I select the range for 7001-7015 for amygdala only, the hippocampal subfields are still there. Is there a way to only load the amygdala nuclei. I'm sure it's something simple I'm just not doing, but I can't seem to get it to work. Any pointers gladly accepted Thanks Erik Erik O'Hanlon Postdoctoral researcher [cid:rcsi-crest-signature_f581c185-1d03-45c8-a786-23d8ece3d391.png] RCSI Psychiatry Royal College of Surgeons in Ireland Beaumont Road, Beaumont D9 Ireland T: 8093740 E: erikohanlon(a)rcsi.ie W: www.rcsi.com<http://www.rcsi.com/> Transforming Healthcare Education, Research and Service: RCSI Strategic Plan 2018-2022<http://www.rcsi.ie/strategy2018> [cid:AS_BRONZE_IIDD_65c26b0a-ea45-42c8-956e-5d84e884e4e6.png]

External Email - Use Caution Dear Bruce, I am very sorry to bother you. We are currently experimenting with freesurfer, but I have encountered a lot of problems during the experiment. We have three resolutions of data, the skull of medium-resolution data can't be removed (neck can't be removed), and with high-resolution data, it will report memory transfer errors. You said before that we can submit data sets to you, how should we provide you with data sets?

External Email - Use Caution Dear Bruce Fischl, Thank you very much for your reply. I checked the effect of going down the skull and found that a large part of the skull has not been removed. The appendix contains images of skull removal. I want to know how we should handle it. yours yujunjie ------------------ Original ------------------ From: "Bruce Fischl"<fischl(a)nmr.mgh.harvard.edu>; Date: Sun, Nov 18, 2018 00:10 AM To: "Freesurfer support list"<freesurfer(a)nmr.mgh.harvard.edu>; Subject: Re: [Freesurfer] Modify defect failed Hi yujunjie the last entry in the log file is: CORRECTING DEFECT 5 (vertices=53772, convex hull=1434, v0=15308) XL defect detected... this is a giant defect - about 1/4 of your total surface. It means that something major went wrong - skull attached, or hemis connected or something. You should look at the rh.orig.nofix and the rh.inflated.nofix surfaces to see what it is. cheers Bruce On Sat, 17 Nov 2018, 1013364183 wrote: > > External Email - Use Caution > > Dear FS, > I ran the recon-all command and it failed to fix it for many days when I fixed the defect.
