Joining Hippocampal files
by Gregorio Borghi 19 Jul '21

19 Jul '21

External Email - Use Caution Dear sir/madam, After the segmentation I obtained the hippocampal segmented file for each hemisphere. Since I want to use them as mask for my functional scans, I wanted to join the the 2 hemisphere files together (otherwise I would obtain a different Multiple comparison computation), but when i tried doing that in FSL (fslmaths) the 2 files were joined but in very different spatial configuration. Is there a way to join the 2 hemisphere file in Freesurfer? -- Kind regards, Gregorio

Drawing ROIs
by Akkoyunlu, Beyza 19 Jul '21

19 Jul '21

External Email - Use Caution Dear FS experts, I am planning to extract early visual region ROIs from my retinotopy scan. Is it possible group vertices according to radian values? (Like it is done in functional scans, filling an area according to the threshold). Or is there any common practice for delineating? Kind regards, Beyza

Obtaining single file from segmented images
by Gregorio Borghi 19 Jul '21

19 Jul '21

External Email - Use Caution Dear sir/madam, I have successfully segmented my participants' hippocampus thanks to "segmentHA_T2.sh" command, which provided me both right and left hippocampal segmented files. However, I was wondering if it is possible to obtain single files for each of the hippocampal subfields (e.g. CA1 and CA3) since I would like to use those files as masks and I need them to be distinguishable. Thanks in advance. -- Kind regards, Gregorio

interscan variability
by AJ 18 Jul '21

18 Jul '21

External Email - Use Caution Hi, I am looking at various brain volumes in the aprarc and aseg stats generated by recon-all and SAMSEG> stats. Some of the subjects were scanned on Philip and some on GE, and some on GE at time point 1 and PH on time point 2. Q1: Is there a measure in the aparc, aseg, and SAMSEG stats files that is fairly resistant to scanner variability? I clearly see eTIV for the same subject have 15% or more discrepancy between GE and PH. Interestingly, cortical thickness relative difference between PH and GE is 1.23% in controls. Q2: Is there a way to harmonize between GE and PH values? Many thanks, AJ

recon -all and mri_convert errors
by Podell, Jamie 17 Jul '21

17 Jul '21

External Email - Use Caution Hi, I am trying to run recon -all on a T1 .nii file and keep running into errors. It says both "No such file or directory" and "bad number of dimensions." Since it seemed to me to be a problem with the .nii file, I tried running mri_convert separately but got the same errors. The file definitely exists in the location I designated (I can open it in freeview, etc.)... Do I need to manually change something about the .nii file to get it to run? Appreciate any help and am hoping there is a simple fix! Here is what the log says: /Users/jamiepodell/Desktop/PSH_MRI/008 \n mri_convert /Users/jamiepodell/Desktop/PSH_MRI/s008_T1.nii /Users/jamiepodell/Desktop/PSH_MRI/008/mri/orig/001.mgz \n mri_convert /Users/jamiepodell/Desktop/PSH_MRI/s008_T1.nii /Users/jamiepodell/Desktop/PSH_MRI/008/mri/orig/001.mgz reading from /Users/jamiepodell/Desktop/PSH_MRI/s008_T1.nii... error: No such file or directory error: niiRead(): bad number of dimensions (10703) in /Users/jamiepodell/Desktop/PSH_MRI/s008_T1.nii Darwin Jamies-MacBook-Pro.local 18.7.0 Darwin Kernel Version 18.7.0: Tue Aug 20 16:57:14 PDT 2019; root:xnu-4903.271.2~2/RELEASE_X86_64 x86_64 Thanks, Jamie Jamie E.

dwi_orig_las issue trac-all -prep
by AmirHussein Abdolalizadeh 17 Jul '21

17 Jul '21

External Email - Use Caution Dear FreeSufer users/experts, I am trying to do TRACULA (FS 7.1.1) on a subject with b = 0,1000 in 60 directions. The preprocessing steps of denoising, bias-field, eddy/motion correction were done using MRtrix (in .mif format) and their outputs are converted into .nii, .bvec, and .bval. I changed the dmrirc.example into the attached file to omit the associated preprocessing steps. Running the trac-all -prep -c dmrirc.pilot results in an error right at the beginning: reading info from /<a long path!>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz... error: niiRead(): error opening file /<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz It is not present in the output folder. Interestingly, this file is generated a few lines above and then renamed into dwi_orig_las and then into dwi.nii.gz: mv -f /<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz /<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.nii.gz A few lines later: mv -f /<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.nii.gz /<path>/AnalyzeDWI/pilot/dmri/dwi.nii.gz Thus, my guess is due to this renames it cannot find it. Any help is appreciated. Bests, Amir p.s. the MRtrix-preprocessed file is itself LAS: orientLAS /<path>/AnalyzeDWI/pilot/dmri/dwi_orig.1.nii.gz /<path>/AnalyzeDWI/pilot/dmri/dwi_orig_las.1.nii.gz INFO: input image orientation is LAS INFO: input image determinant is -8
