PetSurfer analisis whit another atlas
by Matteo Parodi 24 Jul '23

24 Jul '23

External Email - Use Caution Good morning. I try to use surfer analysis with another atas instead of the built-in one. I have an atlas in nifti or mgz format. I tried using it in gtmseg's --head option and it doesn't work, maybe due to normalization issues but I'm not sure. I tried to build the atlas with the utilities in https://secure-web.cisco.com/1npKm2rw7ypoDV5y3qkt0Aa0W2d4IRkHhrWfsjK3gU03P8… but i have problems to interfacing whit gca, gcs and annot file. I searched the mail archive and found no answer. Thank you very much for any input, Parodi.

Re: [Freesurfer] Longitudinal pipeline for FreeSurfer (v7.3.2)
by Jackson Lee 23 Jul '23

23 Jul '23

External Email - Use Caution Hi Yujing, Thanks for your reply – I have a follow up query (see email thread below): I have both a cross-sectional aim and a longitudinal aim I am hoping to explore with FreeSurfer. While they are separate aims, some participants are present in both the cross-sectional and longitudinal arm. Currently I have run recon-all on all participants for my study using the standard recon-all command. As mentioned, I am hoping to do hippocampal subfield analysis (both cross-sectional and longitudinal). I have read both the hippocampal subfield and longitudinal pipelines available from FreeSurfer (linked below): https://secure-web.cisco.com/1_iq2Ortiz8d4uJhrtEXKZ_Row3SgFJsQNSJUW3b3hm3Fp… https://secure-web.cisco.com/1K3vQAJc_XjPimaagPX_W_n-ig3v4kt3fgvsYNoj9HGxxF… I was planning on running the longitudinal recon-all pipeline as it seems that running longitudinal pipeline allows for greater reliability as "the subject is used as their own control". But if I do this, then the subjects that are also in the cross-sectional arm will potentially have different outputs (even though they are the same scan) compared to outputs from the longitudinal pipeline. This would be the same for the subfield analysis. What is the best approach here? Would I be better off running all participants (even those with one T1-weighted scan) with the longitudinal pipeline so that every participant is treated the homogenously? Let me know if I need to clarify anything! Warm regards, Jack Hi Jack, Longitudinal recon-all pipeline is available in Freesurfer 7.3.2. To do longitudinal segmentation using the hippocampal subfield pipeline, it is a requirement that the data have been processed with the longitudinal stream Freesurfer.

Vertex order does not match across fsaverage resolutions
by Alexis Thual 22 Jul '23

22 Jul '23

External Email - Use Caution Hello! As suggested by the latest comment on this freesurfer github issue ( [ https://secure-web.cisco.com/1M0TqndURr2omFNMTTDpuWOzO_Vs7lJWAVS6xceXr6HXZ7… | https://secure-web.cisco.com/1M0TqndURr2omFNMTTDpuWOzO_Vs7lJWAVS6xceXr6HXZ7… ] ), I'm reaching out to you via email. In case that's useful, I'll copy the initial issue here: Problem As detailed in issue #3415 opened in nilearn, vertex order does not match across all fsaverage resolutions. I downloaded fsaverage 3 to 7 tarballs for the git annex of this repo and simply ran the following script to show that vertex order is not preserved across resolutions: # %% from nilearn import surface # %% fs3_path = "/home/alexis/singbrain/data/freesurfer_fsaverage/fsaverage3/surf/lh.pial" fs5_path = "/home/alexis/singbrain/data/freesurfer_fsaverage/fsaverage5/surf/lh.pial" fs7_path = "/home/alexis/singbrain/data/freesurfer_fsaverage/fsaverage7/surf/lh.pial" fs3_coordinates, fs3_faces = surface.load_surf_mesh(fs3_path) fs5_coordinates, fs5_faces = surface.load_surf_mesh(fs5_path) fs7_coordinates, fs7_faces = surface.load_surf_mesh(fs7_path) # %% print(fs3_coordinates[:5]) print(fs5_coordinates[:5]) print(fs7_coordinates[:5]) Output: [[-3.87359581e+01 -1.93433647e+01 6.72201385e+01] [-9.71759605e+00 -9.23328686e+00 4.65803757e+01] [-2.40194092e+01 4.31147995e+01 2.39262428e+01] [-5.98615112e+01 4.93119545e-02 8.97464848e+00] [-5.06454735e+01 -4.94050064e+01 4.78137321e+01]] [[-3.87359581e+01 -1.93433647e+01 6.72201385e+01] [-1.66624870e+01 -6.90612259e+01 6.12812729e+01] [-9.71761799e+00 -9.23326397e+00 4.65803413e+01] [-2.40194283e+01 4.31148720e+01 2.39262142e+01] [-5.98614998e+01 4.92927618e-02 8.97456360e+00]] [[-3.87359581e+01 -1.93433647e+01 6.72201385e+01] [-1.66624680e+01 -6.90612564e+01 6.12812119e+01] [-9.71762943e+00 -9.23325062e+00 4.65803223e+01] [-2.40194435e+01 4.31149139e+01 2.39261990e+01] [-5.98614883e+01 4.92815673e-02 8.97451496e+00]] Here, we see that the second vertex of fsaverage3 doesn't match that of fsaverage 5 and 7. I did some more extensive testing and it seems to me that: fsaverage 5, 6, 7 have consistent vertex order fsaverage 3 and 4's vertex order is different from 5, 6, 7 but can be reworked to be consistent, using a procedure I detailed in nilearn issue #3415 ( [ https://secure-web.cisco.com/1MUOQFQrlxwxUt85m4623j9t2ExzEpzjIm1YZnc6mKLXnd… | https://secure-web.cisco.com/1MUOQFQrlxwxUt85m4623j9t2ExzEpzjIm1YZnc6mKLXnd… ] ) Suggestion Maybe we should reorder fsaverage 3 and 4's vertices for all maps, what so you think? Thank you for the great software anyways! ☺️ Warm regards, Alexis

Sulcal depth maps and pli de passage
by Federica Santacroce 21 Jul '23

21 Jul '23

External Email - Use Caution Hello FreeSurfer Developers, I used the sulcal depth maps superimposed on inflated images (setting colour depth =< 0) to define the morphological sulcal pattern (continuous vs. interrupted). Is this method useful for detecting pli de passage that may be buried deep in the depth of sulcus? [image: sulc.png] In this figure, is it correct to say that when two dark grey segments are adjacent, the sulcus is continuous (e.g. intraparietal sulcus)? On the other hand, when two dark grey segments are separated by a gyrus (light grey), can the sulcus be defined as interrupted (e.g. post-central sulcus)? Thanks in advance, Federica Santacroce

External Email - Use Caution  I think a change was made to the privileges on a single file in the archive.  Gzip subsequently may have changed the modification time in the updated archive and so the checksums could be different.  The checksums listed on the release page are up to date for 7.4.1 under, https://secure-web.cisco.com/1O7GIKohY89IzvrMFWBZrXhqN4gxL7jax2… - R.

Missing chunk in wmparc
by Fahad Hannan 20 Jul '23

20 Jul '23

External Email - Use Caution Hello, Looking at the wmparc.mgz file, there is a chunk in the top right frontal region that does not show up as part of the segmentation. I figured I needed to add control points through Freeview in case the chunk was not included as part of the brain. However, in Freeview it shows it included in the segmentation. Images attached show the brain in 3Dslider where the chunk is not segmented, and Freeview showing rl/lh.white and rl/lh.pial overlayed. Regards, Fahad
