The volume of some hypothalamus subunits is 0
by Xiaotong Zhang 12 Jan '22

12 Jan '22

External Email - Use Caution Hello FreeSurfer Developers, When I used the FS.dev version for hypothalamus segmentation, I have segmented it sucessfully. Tensorflow-CPU has been installed to run this module (hypothalamus_seg). The .sh file was: for subj3 in 111 112 114...and 431 do mri_segment_hypothalamic_subunits --i /run/media/guanliyuan/Elements_Learningmaterials/try3_fs/$subj3/mri/orig/001.mgz --o /run/media/guanliyuan/Elements_Learningmaterials/try3_fs/try3fs_seg/$subj3/ --vol /run/media/guanliyuan/Elements_Learningmaterials/try3_fs/try3fs_seg/$subj3/ --threads 1 --cpu done However, in the .csv file of some subjects, there were no the volume of the left and right anterior-inferior. I don't know the reason for this cese. I am looking forward to your reply. Thanks very much in advance. Please check attachment about the results of hypothalamic_subunits 1) FreeSurfer version: freesurfer-linux-centos7_x86_64-dev 2) Platform: CentOS 7.9 Sincerely, Zhang

In Ubuntu linux, run the terminal program, and use these commands to try and directly install freesurfer. (There is also some documentation under https://secure-web.cisco.com/16yf-9jnI1XE2VTPlodTjL4JQ0cg__EgJTUM4KJe7m5QTs… Get the 7.2.0 installer with, $ cd $ wget  https://secure-web.cisco.com/1Axw7MVZbtZg7DWF1xSXkEcIDLIFHbL30xZStvae83fDk2… Then try the install with the .deb file, $ sudo apt-get update $ sudo apt-get install ./freesurfer_7-dev_amd64.deb .... answer Y/yes to prompts .... Do you want to continue?

Doubts about mri_fdr
by Laura Willers de Souza 11 Jan '22

External Email - Use Caution Hi, I was already discussing my doubts with Douglas here https://secure-web.cisco.com/1UDGfmmgTwXKhhYWoGJSmyTRYLt6xQw2AQ1oLFEdo13Hp2…, but for some reason my emails stopped going to the mailing list. So I'm sending what was left open. So which file do I put as an argument to --thfile? Or I just don't put the --thfile? And about that tool to convert the table into a map. That's what appeared in that link you sent me. [cid:8ba3ee60-644b-4fa0-9d4e-925fd659cbde] Do I run the second line to get the tool?

When mri_glmfit finishes it generates the sig.table.dat file which has the p values of the ROIs (first image below). Then, when mri_fdr finishes, that same sig.table.dat file no longer contains the p-values of the ROIs, but the FDR value (second image). In this way, the p-values of the ROIs are lost. What I would like is to end mri_fdr with a file with the value of fdr + the original sig.table.dat file with the p values of the ROIs. Is there a way to do this?

But, in the end, the file that contains the thresholds for each of the ROI (first image below) ends up being replaced by the FDR value (second image below), which is not very good, because this information ends up getting lost. I don't understand what you mean. The value in the file is the threshold that you would use to divide your ROIs into significant vs nonsig groups in a way that meets the FDR criteria; in your case, it looks all but subiculum will pass. Or are you looking for an FDR-corrected p-value for each ROI? Is there any way to save the FDR value in another file and not in the same one where the p-values of the ROI are? And is it possible to visualize the ROIs with the significance scale in freeview? I tried to overlay the sig.mgh file over the inflated surface and also the mri_fdr output.mgh file, but it didn't work. That definitely will not work. What should I do to make this work? You have to convert the table into a map.

Hippocampal segmentation - data processed in different fs version
by Katarina Vulić 10 Jan '22

External Email - Use Caution Hello Freesurfer Developers, We have data that has been initially processed by Freesurfer v6.0.1. Is it ok if we run hippocampal subfield segmentation ( https://secure-web.cisco.com/1jE-n3Hq6P8vcsBZUmGPkR42g9WznVSWKUxrDeSXYoSnRi…) with v7.1.1 that we currently have on our machine?

mkheadsurf error: mris_smooth and mris_inflate synthesized bizarre output paths
by Yong-Jun Lin 09 Jan '22

09 Jan '22

External Email - Use Caution Hello FreeSurfer Developers, I was attempting to execute the mkheadsurf script to process MRI data and encountered some errors. 1. The first error message is "subjdir: Undefined variable.". After reading through the mkheadsurf script, I realized that is a temporary variable used in a script. Having no idea why this was required in the beginning, I manually entered export subjdir=/Volumes/Lab/SA/MRI/ForMNE/subj01 to circumvent that problem. 2. Indeed the script started running afterwards, but there were two errors at step 1. (Creating a dense scalp tessellation with mkheadsurf) First, mris_smooth -n 10 -b /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/area.seghead -c \ /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/curv.seghead \ /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/lh.seghead \ /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/lh.seghead resulted in error: MRISwriteCurvature: could not open lh./Volumes/Lab/SA/MRI/ForMNE/subj01/surf/lh.curv.seghead Second, mris_inflate -n 10 -sulc /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/sulc.seghead \ /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/lh.seghead \ /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/lh.seghead.inflated resulted in error: MRISwriteCurvature: could not open /Volumes/Lab/SA/MRI/ForMNE/subj01/surf/lh./Volumes/Lab/SA/MRI/ForMNE/subj01/surf/lh.sulc.seghead Please note that the weird output paths have the output folder repeated twice in different positions. I've searched the list and no similar errors have been reported. Does anyone have any thoughts on how to trouble-shoot this one? Also, I've attached the mkheadsurf.log in case it's of any use. 1) FreeSurfer version: freesurfer-darwin-macOS-7.2.0 2) Platform: macOSX 10.13.6 3) uname -a: Darwin localhost 17.7.0 Darwin Kernel Version 17.7.0: Fri Oct 30 13:34:27 PDT 2020; root:xnu-4570.71.82.8~1/RELEASE_X86_64 x86_64 4) mkheadsurf.log: see attached Sincerely, -- Yong-Jun Lin Postdoctoral Associate Department of Psychology New York University 6 Washington Place, Room 955 New York, NY 10003 -- Yong-Jun Lin Postdoctoral Associate Department of Psychology New York University 6 Washington Place, Room 955 New York, NY 10003
