Creating or Using Alt Templates
by Olivier Brown 29 Nov '22

29 Nov '22

External Email - Use Caution Dear Freesurfer experts, I am using a pediatric sample for my study. I understand that the default template has been used with younger samples in the past. However, is there a command or flag to input an external template, such as the MNI? Otherwise, is there a method for creating my own template using the acquired imaged with Freesurfer? I cannot seem to find many resources online for selecting alternate templates in the preprocessing steps of recon-all. Warm regards, Olivier Brown

time-series from Yeo's Network components
by stdp82＠virgilio.it 29 Nov '22

29 Nov '22

External Email - Use Caution Hi list, I would extract the rs-fMRI time-series from spitted components of Yeo's 7 Network Atlas (fsaverage5). To this aim, I'm planning to convert the "fmcpr.odd.sm0.fsaverage.lh.nii.gz" (obtained by preproc-sess) on fsaverage5. However, the fmcpr.odd.sm0.fsaverage.lh.nii.gz should still include some nuisance variables (CSF, the white matter, motion, first 4 time points). To address this issue, is it corrected to apply the command lines reported below? mkanalysis-sess -analysis fc.noseed.surf.lh -surface fsaverage lh -fwhm 0 -notask -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -polyfit 5 -nskip 4 -mcextreg -fsd rest -TR 1.67 -per-run -hpf 0.01 -lpf 0.1 -nowhiten mkanalysis-sess -analysis fc.noseed.surf.rh -surface fsaverage rh -fwhm 0 -notask -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -polyfit 5 -nskip 4 -mcextreg -fsd rest -TR 1.67 -per-run -hpf 0.01 -lpf 0.1 -nowhiten selxavg3-sess -s subj_folder_name -a fc.noseed.surf.lh -overwrite -no-con-ok selxavg3-sess -s subj_folder_name -a fc.noseed.surf.rh -overwrite -no-con-ok Thanks Stefano

Tracula multiple fatal errors: Eddy and MRI binarize (thalamic segmentation)
by Ward Deferm 29 Nov '22

29 Nov '22

External Email - Use Caution Dear Freesurfer developers, I am attempting to perform tracula on a single participant but i am running into multiple fatal errors during trac-all prep. The first fatal error is this one : eddy_openmp --imain=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/dwi_orig_las.nii.gz --mask=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/lowb_topup_brain_mask.nii.gz --bvecs=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/dwi_orig_las.bvecs --bvals=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/dwi_orig_las.bvals --acqp=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/acqp.txt --index=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/index.txt --data_is_shelled --topup=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/topup --out=/Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/dwi eddy_openmp: Command not found.

If i change the config file to set doeddy = 1 to work with eddy correct this error disappears. But I would prefer to use eddy here instead is there any way to fix this. Further along i get another fatal error in the mri binarize part of the code which is related to a previous issue found in the mailing archives (https://secure-web.cisco.com/1eL0pyxEECqHmJx6yIaWdwio_XR8d47T_BB4CncFLEYAt8… Applying LTAtransformInterp (resample_type 0) writing to /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dlabel/diff/White-Matter++.bbr.nii.gz... mri_convert -at /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/xfms/anatorig2diff.bbr.lta -rt nearest /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dlabel/anatorig/aparc+aseg+thalnuc.nii.gz /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dlabel/diff/aparc+aseg+thalnuc.bbr.nii.gz mri_convert -at /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dmri/xfms/anatorig2diff.bbr.lta -rt nearest /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dlabel/anatorig/aparc+aseg+thalnuc.nii.gz /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dlabel/diff/aparc+aseg+thalnuc.bbr.nii.gz reading from /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dlabel/anatorig/aparc+aseg+thalnuc.nii.gz... error: niiRead(): error opening file /Users/r0755008/Desktop/mri_data/TRACULA/NT001/dlabel/anatorig/aparc+aseg+thalnuc.nii.gz Darwin gbw-d-m0128.luna.kuleuven.be 21.6.0 Darwin Kernel Version 21.6.0: Thu Sep 29 20:12:57 PDT 2022; root:xnu-8020.240.7~1/RELEASE_X86_64 x86_64 trac-preproc exited with ERRORS at Tue Nov 29 13:24:02 CET 2022 I wanted to try the proposed solution but i have no permission to edit the files as specified in the thread. Would there be another fix for this. In the attachment you can find the log and error files of both runs (1 is the eddy error, 2 the mri binarize) and the config file I used. I am using freesurfer 7.2.0 platform MacOS Monterey 12.6.1 Kind regards, Ward Deferm CDP KU Leuven
