mris_convert reading surf.gii files?
by Westin, Karin 04 Mar '24

04 Mar '24

External Email - Use Caution Hi I'm trying to create an .annot file from a label.gii file using an HCP fsavarage.surf.gii file (eg mris_convert --annot my_label.label.gii fsaverage_template.L.surf.gii lh.my_annot.annot). However I keep getting the error ** failed to open GIFTI XML file 'fs_L-to-fs_LR_fsaverage.L_LR.spherical_std.164k_fs_L.surf.gii' mrisReadGIFTIdanum: gifti_read_image() returned NULL Is there a better way to read/open CIFTI files using mris_convert? Best and thanks Karin

Re: [Freesurfer] Subject does not have a bstampfile

External Email - Use Caution   Let me add that it will not work to use shared mount point from the Windows filesystem as you list below, /mnt/c/Users/GCM/Desktop/subjects/NowakG/mri - for your SUBJECTS_DIR when running a recon-all command.  The command will fail because the Windows file system does not support soft-links.   Any SUBJECTS_DIR used for recon-all needs to be inside the Linux OS image running freesurfer.  You could however copy the files from that mount point to create another SUBJECTS_DIR somewhere inside your Linux image, e.g., under your home directory in linux. .... in your linux terminal window ... $ cd$ mkdir subjects$ export SUBJECTS_DIR=$HOME/subjects$ cd $SUBJECTS_DIR$ cp -p -f -R /mnt/c/Users/GCM/Desktop/subjects/NowakG . - R.

Longitudinal Freesurfer in the presence of large tissue defects
by Philip P 04 Mar '24

04 Mar '24

External Email - Use Caution Dear Freesurfer Developers, I am currently running the Longitudinal Pipeline on a cohort with significant portions of brain tissue removed. The obtained base templates overall look reasonable, however, when overlaying the transformed session T1ws and flicking between them, there still are noticeable residual differences. This is not surprising, given the inevitable brain shift after tissue removal, which rigid registration cannot account for. In my search for a non-linear base template option I came across the "Longitudinal FreeSurfer with non-linear subject-specific template improves sensitivity to cortical thinning” ISMRM abstract (https://secure-web.cisco.com/1me4RY0enlek75e3PAqIseSGOO7tfF84eBwPlWXYndHKO5…) as well as related code on Github (https://secure-web.cisco.com/10WRpCPnvc4D9H2TOaZHsTUn0u7cWtVKoReU9EtexFnzvs…) I was wondering whether you could provide insights into what you think the best strategy for obtaining reliable longitudinal cortical thickness measurements in such a dataset. Do you have a feel for whether the Longitudinal Freesurfer processing stream still provides benefits over Cross-Sectional analysis in the presence of large defects? Would you recommend giving the above-mentioned non-linear implementation a shot or were there other reasons the feature has not been implemented yet in the official version? Thanks already in advance! Best Philip

control points do not help with pial and white matter edits to frontal areas with atrophy
by Lydia Chung 03 Mar '24

03 Mar '24

External Email - Use Caution Hi Freesurfer Team, I have a pt with significant atrophy in the right orbitofrontal/rostral middle frontal area (see screenshots below). I have added several control points but this has not been successful, as there is not much white matter in that area to begin with. Do you have recommendations for dealing with this type of issue? Do you typically leave as is or discard the subject entirely?

Is the slice delay of each slice needed for slice time correction with preprocess-sess?
by Maria Hakonen 03 Mar '24

03 Mar '24

External Email - Use Caution Dear all, Have I understood correctly that the slice delay of each slice is not needed when performing slice time correction with preprocess-sess? I am processing an open OASIS fMRI dataset. The dataset has fMRI data in nifti format and JSON files that contain information about the data. In the instructions they say: "Slice timing is included in the JSON when available. Some original DICOM files did not have slice timing info. When slice timing information is unavailable use the ratio TR/#slices." The data is collected with a Siemens scanner. If the slice timing is available it seems to be interleaved: "SliceTiming": [ 1.1025, 0, 1.165, 0.059999999999999998, 1.2250000000000001, 0.1225, 1.2875000000000001, 0.1825, 1.3474999999999999, 0.245, 1.4099999999999999, 0.30499999999999999, 1.47, 0.36749999999999999, 1.5325, 0.42749999999999999, 1.595, 0.48999999999999999, 1.655, 0.55000000000000004, 1.7175, Could I just run slice time correction with the siemens option? Best regards, Maria

Vertex / voxel lesion symptom mapping
by Martin Juneja 03 Mar '24

03 Mar '24

External Email - Use Caution Greetings FreeSurfer community, I was just wondering if it's possible to perform vertex/voxel lesion symptom mapping (VLSM) using FreeSurfer? In other words, I would like to assess the impact of lesion topography (of course, heterogenous locations across patients) on neurocognitive function in brain tumor patients. I would greatly appreciate any help/response. Thanks!

External Email - Use Caution Good morning, 1) For the Samseg protocol, are only T1 and FLAIR sequences required (no MPRAGE scans required)? 2) What does the numerical output of the Samseg calculation look like? Best regards, Krzysztof Barć

Creating a custom registration template with FreeSurfer template
by Asuka Toyofuku 29 Feb '24

29 Feb '24

External Email - Use Caution Dear Freesurfer experts, I have issues with creating a custom registration template. (I'm following this instruction: https://secure-web.cisco.com/1_qfYxT5WNAR-lGRNh895Kl4pqE513hIRdGqZt0w-oDRR8… ) According to the instructions, we need to 1) Create an average subject (Creates $SUBJECTS_DIR/newtemplate) 2) Register each subject to the new template (do for both lh and rh), resulting in lh.sphere.reg.newtemplate and rh.sphere.reg.newtemplate 3) Get thickness values in the newtemplate space for GLM analysis 4) Create another average template based on the previous one: (Creates $SUBJECTS_DIR/newnewtemplate) I'm stuck with the 3) command. Instruction suggests: mris_preproc --surfreg sphere.reg.newtemplate --s subj1 --s subj2 --s subj3 ... and this is my code: for d in Teen* do mris_preproc --surfreg sphere.reg.teenheart_average_template --s $d --hemi lh --out lh.surfreg.teenheart_average_template.thickness --meas thickness done ( I specified hemi and output because, without it, I got ERROR: no source hemi specified) My command led to an error saying: ERROR: format for lh.surfreg.teenheart_average_template.thickness not recognized So my questions are: a) what does it mean that "format for lh.surfreg.average_template.thickness not recognised"? Any ideas on how to fix this? b) Does this mris_preproc --surfreg command produce different smoothing mgh files? (e.g., fwhm10, fwhm15, fwhm20...?) Because standard mris_preproc before GLM analysis(https://secure-web.cisco.com/1lH2n5girv1pSO3WmL3I9nDeL07oFU0ViiAmz… are done with previously qcashed data (e.g., need thickness.fwhm10.fsaverage to run mris_preproc), but at this point, I don't have any of these thickness files with different smoothing levels. c ) If this mris_preproc --surfreg command does not generate a set of thickness maps in **newtemplate space** at different smoothing levels, what kind of command should I run? Any input is appreciated! Best regards, Asuka
