Tessellation: factors that could affect number and size of faces
by Avideh Gharehgazlou 22 Nov '17

22 Nov '17

Dear FreeSurfer experts, I have a question regarding the tessellation step, in which the surface is covered by a mesh of triangles. 1. How would the number/sizes of triangles be affected/ alter as a result of different brain volumes/sizes of different subjects? i.e. would a subject with a bigger brain volume have greater number of triangles compared to a subject with a smaller brain volume? Or will the subject have the same number of triangles, but larger triangles instead? 2. I am aware that the triangles are not uniform like the voxels in a VBM... within a particular subject, how are the sizes of triangles determined in different parts of the brain? What determines which parts of the brain will have smaller/larger triangles compared to other parts of the brain? Would really appreciate your input, Thanks, Avi CONFIDENTIALITY NOTICE: This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

Skullstrip commands not working
by Arsenije Subotic 21 Nov '17

21 Nov '17

Dear experts, I recently finished processing a subject for whom I had performed a skullstrip on the brainmask volume. I decreased the watershed parameter and re-examined the brainmask and the portion of the skull was gone, although some dura was left over. I did a recon-all using the following command: recon-all -autorecon-pial -subjid <subject name> However, when recon was finished, I noticed that the skull re-appeared and the surfaces were outlined on it. I went back and tried g-cut to remove the little dura that was left over, but that also did not work. I tried varying the watershed parameters again but I keep getting the same result. Is there any other underlying issue that may be at fault? Thanks for your help, Arsenije

Re: [Freesurfer] T1 and brainmask wonky: Pieces of putamen missing

Update to my first email: Hello again FS Developers and anyone experiencing the same problems, A colleague of mine has found what we think has already been addressed in the following link: https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2016-November/048666… >From the sounds of it, this doesn't seem to be a real issue; however, I would love to better understand why this doesn't matter in the long run, i.e. why the brainmask does not later affect parcellation of subcortical regions(?). Thank you for your time! Diana

hippocampal subfields stats
by Donatas Sederevicius 21 Nov '17

21 Nov '17

Dear Freesurfer Developers, I’ve run the new longitudinal hippocampal subfields segmentation using Freesurfer’s developer version. Then I decided to extract stats for each hierarchy: HBT, FS60 and CA. I used the following command, for example: mri_segstats —seg lh.hippoAmygLabels-T1.long.v20.CA.mgz —ctab-default —sum output.txt I got what I wanted but decided to compare the results of one subject for Hippocampal_tail for each hierarchy and with the text file lh.hippoSfVolumes-T1.long.v20.txt. I got the following volume values: lh.hippoSfVolumes-T1.long.v20.txt: 583.65 HBT: 593.4 FS60: 593.4 CA: 598.3 I wonder how do you actually extract stats that are present in lh.hippoSfVolumes-T1.long.v20.txt file? What is the reason for different values? I’m very curious since I cannot get the exact same stats as in the lh.hippoSfVolumes-T1.long.v20.txt file. Thanks a lot! Donatas

Problems when loading surface and mesh showing vertices
by Rosalia Dacosta Aguayo 21 Nov '17

21 Nov '17

Dear FreeSurfer Developers, I am checking the OutputData_freeview after running recon-all following your tutorial: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/OutputData_freeview I have loaded T1.mgz, wm.mgz, brainmask.mgz and aseg.mgz, and then the surfaces: rh.pial, rh.white, lh.pial and lh.white. In general, I did not see any problem...but when I wanted to see the surface&mesh with vertices I saw something estrange I do not know if it is a problem or it is normal (see the vertices in the temporal pole in grey scale)...as this is my first run with FreeSurfer. I attach you the image. 1. FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c 2. Platform: CentOS release 6.7 3. uname -a: Linux rosalia-PORTEGE-Z930 4.4.0-98-generic #121-Ubuntu SMP Tue Oct 10 14:24:03 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux 4. Recon-all.log; see attached (although it ended without errors) I haven't come across this error in my searches, but I may be using the wrong key terms. Would anyone be able to point me in the right direction or trouble-shoot fixing this? Thank you for your time, Rosalia

fsaverage template appropriate to use with pediatric population?
by Avideh Gharehgazlou 21 Nov '17

21 Nov '17

Hi experts, I have a few questions regarding the use of fsaverage template for my research: 1. Is the fsaverage template appropriate for use with pediatric population? (My sample is 6-16 years of age) 2. What possible errors can be expected ? What could possible alignment errors be? 3. Are there any regions I should expect to have more errors in?

Problems after running recon-all ...-qcache
by Rosalia Dacosta Aguayo 21 Nov '17

21 Nov '17

Dear FreeSurfer Developers, I have run recon-all....-qcache after reviewing the recon-all...-all outputs in freeview..... I have been looking into: https://surfer.nmr.mgh.harvard.edu/fswiki/mris_preproc Now it seems that I could have omitted the -qcache...and I am a bit lost with the examples showed in the link. Any one could help me regarding the concatenation and how to created the FSGD file? Taking into account I would like to run a cortical thickness analysis between three groups, how I should run the ANOVA? Finally, should I have into account General Atrophy Measures such as: global average thickness for both hemispheres, only or in combination with estimated global intracranial volume as a nuissance regressors in the design? So = ANCOVA instead of ANOVA. Does anyone have any thoughts on how to trouble-shoot those problems? Kind regards, Rosalia
