Matlab crash dump when running the segmentation of longitudinal hippocampal subfields
by Liu Guodong 30 Sep '19

30 Sep '19

External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to analyze longitudinal hippocampal subfields for many subjects on a server, but when I run the command longHippoSubfieldsT1.sh, for some subjects, I get the error for Matlab and a file called matlab_crash_dump. I've searched the list and no similar request have been submitted. Does anyone have any thoughts on how to solve this problem? Also, Ive attached the matlab_crash_dump file. 1) FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0 2) Platform: CentOS release 7 3)matlab_crash_dump file: see attached Best regards, Guodong

Libraries not found Freeview ubuntu 18
by Renew Andrade 29 Sep '19

29 Sep '19

External Email - Use Caution Dear FreeSurfer experts: I have a problem with Freeview running I ubuntu. Some libraries missing. I read this thread “https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg63255.html <https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg63255.html>” and my question is regarding the installation of the libraries. Do I need to install manually one by one or is there any package to install most of them? Plus I couldn´t find any of them by the name in "sudo apt-get install *”. Some of them are OpenGL, qtscript, volumerendering, vtkftgl, vtkhybrid, vtkIO, vtkDICOMParser, ...

Converting .label coordinates to MNI
by Berger, Joel 27 Sep '19

27 Sep '19

External Email - Use Caution Hi friendly Freesurfers, I have seen this question asked, but can't find the answer. When exporting a label from tksurfer for a particular ROI for a subject, the coordinates in the .label document don't match up with any of the coordinates I can view in tksurfer. Is there a way/formula to convert these easily, ideally into MNI coordinates? I tried loading the label into Matlab with freesurfer_read_label.m converting to Talairach with freesurfer_label2tal.m and then also converting those coordinates using tal2mni.m, but the Talairach or the MNI coordinates do not match with the Talairach/MNI coordinates shown for the corresponding vertices in tksurfer.

TRACULA - input Nifti instead of DICOM?
by Daniel Callow 27 Sep '19

27 Sep '19

External Email - Use Caution Hello I was given a dataset already in Nifti format that I would like to run Tracula on. Is it possible to input Nifti files in the config file instead of DICOMs? How would this work?

Which files do I need to mri_deface to anonymized a subject?
by Tim Schäfer 27 Sep '19

27 Sep '19

External Email - Use Caution Dear FS experts, I want to upload neuroimaging data pre-processed by FreeSurfer's recon-all pipeline to a consortium server, and they require all data to be anonymized. I found mri_deface [1] and wondered which files I would have to apply it to, and whether there are any other things I should be aware of. So far, my plan is to use mri_deface to replace, for each subject, the following files in mri/: * orig.mgz * orig_nu.mgz * T1.mgz * rawavg.mgz It would also be an option to upload only a subset of all the files produced by FreeSurfer, but I do not know which files to exclude and include, so if you have suggestions for this, it would also be very welcome. I will also look at some public datasets to see how they did it.

Re: [Freesurfer] Error during processing data. mris_make_surfaces malloc: *** error for object 0x2431900024317: pointer being freed was not allocated.

External Email - Use Caution Dear Bruce, I don't’ know exactly what happened during the processing. I have 8 Gb of RAM of my Mac. When the freesurfer is working there is approximately 2 Gb free RAM. Unfortunately, I don’t know how to check the working of RAM and was there a memory overflow or memory leaking. It will be great If you could check my data. I want to mention that the same problem was with other data of the same patient. I have uploaded the patient data on my google drive account. So here you can download it https://drive.google.com/file/d/1Rx2HG2ZXTTphrYDMRwguOljz9T4K7av1/view?usp=…. The error appeared for data for 2019-07-22. But the same problem appeared for data for 2019-09-04. mris_fix_topology(5832,0x7fffc83843c0) malloc: *** error for object 0x7fcf88f2ca50: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug 0 defective edges Abort Darwin mac-2ap023-2.fccho-moscow.ru<http://mac-2ap023-2.fccho-moscow.ru> 16.7.0 Darwin Kernel Version 16.7.0: Thu Jan 11 22:59:40 PST 2018; root:xnu-3789.73.8~1/RELEASE_X86_64 x86_64 recon-all -s 2019-09-03_3DBrainView_T1_FSSD_2019-09-26_13-11 exited with ERRORS at Thu Sep 26 17:43:07 MSK 2019 To report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting I saw the system requirements for the freesurfer and there was a mention about 8 RAM. Is it a necessary amount of memory only for freesurfer or for PC station? Best regards, Anton Troitskii. Are you running out of memory on the machine? If not, and you upload the entire subject dir we will see if we can replicate and fix this problem. cheers Bruce On Tue, 24 Sep 2019, Троицкий Антон Александрович wrote: External Email - Use Caution Hello FreeSurfer Developers, during the processing of patient data an error occurred.

Hippocampus Subregion
by ZZY 26 Sep '19

External Email - Use Caution Dear Freesurfer experts,                I got the volume of hippocampal subregions by using the command -  "recon-all -all -s bert -hippocampal-subfields-T1" in Freesurfer. How do I get the surface-level metrics of the hippocampal subregions (e.g., area, thicknness and curve) in the T1 mage? Best, Zhiyong
