amygdala segmentation using additional scan error
by 오진영 27 Sep '18

27 Sep '18

External Email - Use Caution Hello, freesurfer experts I'm trying to run segmentation of hippocampal subfields and nuclei of amygdala with additional scan. I already ran segmentation of hippocampal subfields and nuclei of amygdala with only T1 image, using segmentHA_T1.sh command and succeeded. After success of segmentation of amygdala with T1 image, I tried to run segmentation again with additional scan(T2 image) to get more reliable results. However, when I use command segmentHA_T2.sh, I got the following error: Error in segmentSubjectT1T2_autoEstimateAlveusML (line 2628) And the last few lines before the error are below: *Fitting mesh to image data mask took 264.2808 seconds* *Transforming points* *Transforming points* *Wrote image to file image1.mgz* *Wrote image to file image2.mgz* *INFO: dst volume info differs from the one stored in lta. gets modified now.* *volume geometry:* *extent : (232, 469, 208)* *voxel : ( 0.3333, 0.3333, 0.3333)* *x_(ras) : ( 0.0000, -1.0000, 0.0000)* *y_(ras) : ( 0.0000, 0.0000, -1.0000)* *z_(ras) : ( 1.0000, 0.0000, 0.0000)* *c_(ras) : (-21.1788, -1.8961, 3.8447)* *file : T2isotropic.mgz* *volume geometry:* *extent : (256, 256, 256)* *voxel : ( 1.0000, 1.0000, 1.0000)* *x_(ras) : ( 0.0000, -1.0000, 0.0000)* *y_(ras) : ( 0.0000, 0.0000, -1.0000)* *z_(ras) : ( 1.0000, 0.0000, 0.0000)* *c_(ras) : ( 2.3212, 8.6039, -21.1553)* *file : /Users/mnd_mac/Desktop/JY_surfer/sub_05_T2.nii* *Constructing image-to-world transform from header information (asmr1.mgz)* *Constructing image-to-world transform from header information (/Users/mnd_mac/Desktop/JY_surfer//recon_sub_05/tmp/hippoSF_T1T2_v21_T2_left/imageDump.mgz)* *Wrote image to file asmr2.mgz* *This file does not contain MRI parameters* *This file does not contain MRI parameters* *This file does not contain MRI parameters* *In an assignment A(:) = B, the number of elements in A and B must be the same.* *Error in segmentSubjectT1T2_autoEstimateAlveusML (line 2628)* *MATLAB:subsassignnumelmismatch* *Darwin MnD-macui-iMac.local 17.7.0 Darwin Kernel Version 17.7.0: Thu Jun 21 22:53:14 PDT 2018; root:xnu-4570.71.2~1/RELEASE_X86_64 x86_64* and I have no idea how to solve this problem out. I use the dev version of freesurfer. T1 scan image and T2 scan image of participant were taken on the same day. If you have any recommendations, please send me the email back. Thanks! Jinyoung

Extra sub-cortical mass
by Alec Siegel 26 Sep '18

26 Sep '18

External Email - Use Caution Hello, I'm a computer science student interested in 3D printing a model of my brain. I've successfully used freesurfer to create STL files of both my cortical and sub-cortical regions. Everything looks good except for some non-symmetrical excess mass below my cerebellum on my sub-cortical file. I'm certainly no neurologist, but it doesn't look quite right to me. I would appreciate it if someone would point out I can correct this, I am certainly willing to provide any needed files. Thanks, Alec Siegel

In case this is helpful, using a Docker (such as below), might be a helpful solution for reducing cross-platform reproducibility issues: https://mindboggle.readthedocs.io/en/latest/ -- Arkadiy L.

WM edits
by Alexopoulos, Dimitrios 26 Sep '18

26 Sep '18

External Email - Use Caution I'd like to make edits to correct the superior regions where then pial surface truncates WM (images below). Would it be more useful to use controls points in the WM or add WM to the wm.mgz.

Cortical ribbon and the hippocampus
by Alon Baram 26 Sep '18

26 Sep '18

External Email - Use Caution Hello, I'm trying to understand what do the files ?h.ribbon.mgz include as part of the ribbon mask. It's obvious they include all the GM between the white and pial surfaces, but they also include some voxels which are not GM (according to aparc+aseg.mgz). For example, ?h.ribbon seems to include some of the hippocampus, but not all of it (seems to me like it's the ventral/inferior part that is included). How is it decided what is included in ?h.ribbon and what isn't? Thanks!

Re: [Freesurfer] Reporting Cohen's D for a significant cluster
by Maksimovskiy, Arkadiy 26 Sep '18

26 Sep '18

Hi Bruce, I wanted to follow up on this as I was unsuccessful in doing what you suggested using Freeview (2.0)- entering numbers into the window does not change anything. Might there be another way to find out the Cohen’s D? Thank you for your help, Arkadiy -- Arkadiy L.

amygdala segmentation atlas influence
by Emily K Clarke 26 Sep '18

26 Sep '18

External Email - Use Caution Hello all, I have run the amygdala segmentation in my datasets to obtain volumes of nuclei. I am aware from the fswiki that the volumes should be interpreted with caution because of the reliance on the atlas. When running FS, is there a way to get some metric about how much the segmentation relied on the atlas relative information from the T1 being segmented. If this metric is not available to the user, is some version of it calculated by the software and therefore available internally. Thanks in advance for your help! raj
