External Email - Use Caution Hi I tried to running recon all on a large amount of data and got the below error message. the listed files that say the tag image orientation can't be found aer in the folder but seem to be blank. i was wondering is there a way to run recon all and skip/ignore those seemingly blank files or should i delete them from the folder? Thanks [image: error_message.png]

Surface-based smoothing of EPI data
by Mason Wells 28 Nov '21

28 Nov '21

External Email - Use Caution Hi Experts, This question may have been addressed elsewhere on the list, but I can’t find a response. I want to smooth BOLD data on the surface. First, I pre-processed the data in FEAT with no smoothing applied. Then I registered the filtered_func data to the anatomical using bbregister. I check the registration matrix looks good by running this command (using example_func as the reference): * tkregisterfv --mov example_func.nii.gz --reg junk.dat --lta reg/freesurfer/anat2exf.register.dat --surfs I then resampled my data with mri_vol2surf using the following command: * mri_vol2surf --src filtered_func_data.nii.gz --out lh_func_native.mgh --srcreg reg/freesurfer/anat2exf.register.dat --hemi lh --projfrac 0.5 --out_type mgh I then want to smooth this data on the surface. I assume it would be best to run mri_surf2surf and set the target and source subject as the same? Such as this command: * mri_surf2surf --srcsubject sub-0006 --srcsurfreg lh.sphere.reg --trgsubject srcsubject --trgsurfreg sphere.reg --hemi lh --sval lh_func_native.mgh --tval lh_func_native_smoothed.mgz --mapmethod nnf --fwhm 5 --cortex Please can someone on this list give me some advice on this? Are my command suitible and/or am I missing anything?

Can't load ROI labels
by Shapiro, Noah Lorenz 28 Nov '21

28 Nov '21

Hello, I am very new to FreeSurfer, and I was going through the tutorials and bumped into difficulties when loading ROI's. I can load volumes (e.g. orig.mgz) in Freeview; however, I can't load any ROIs. I can select a label (e.g. lh.BA45_exvivo.label) and hit "open", but then nothing happens. The label doesn't load at all. I don't get an error message either. I am using FS version 5.3, and I also tried on FS version 6. Quartz is updated. I am running on macOS Big Sur version 11.6. Do you have any ideas why I can't load ROI labels? Any help is highly appreciated. Best wishes, Noah Noah Shapiro Research Technician (II) Department of Neurology Alzheimer’s Clinical & Translational Research Unit Massachusetts General Hospital 149 13th Street Charlestown, Massachusetts 02129 E-mail: nlshapiro(a)mgh.harvard.edu

Help
by Nilab Nasrullah 28 Nov '21

28 Nov '21

External Email - Use Caution Hi, I am editing subjects for a research project. After reconstruction, some parts of the brain are not included in the segmentation. Often, some parts of the temporal lobe and the cortex of the occipital lobe are not included. In some cases, the cortex of the frontal lobe is also affected. I have tried using controls points, but the results don't change. I have also reconstructed them again, running autorecon1 and autorecon2&3 separately. I have lowered the watershed parameters, used the gcut command and edited manually after autorecon1 but in the end, the results don't vary significantly compared to running recon-all -all. What can I do to include the missing parts? Thanks, Nilab När du skickar e-post till Karolinska Institutet (KI) innebär detta att KI kommer att behandla dina personuppgifter.

External Email - Use Caution Hi Experts, My tracula completed with no error. So I was trying to view the fa.nii with the following command: freeview -v mri/brain.mgz mri/orig.mgz mri/wmparc.mgz:colormap=lut:opacity=0.2 dmri/dtifit_FA.nii:reg=touch/rusage.mri_ca_register.dat:colormap=heat:heatscale=.2,.2,1 -colorscale -viewport coronal. It returned with an error message saying: "reading registration failed". I have looked at the register.dat from the following link: RegisterDat - Free Surfer Wiki (harvard.edu) <https://secure-web.cisco.com/1hv0bANzHoBn4ULec2TL4BHOCLGLVTqseZKeSEib8vKA0k…>. My register.dat is nothing like that (attached below). So where should the file locate? Best, Jackie

Difficulty Running Single Subject Surfaced Based GLM

28 Nov '21

External Email - Use Caution Hello FreeSurfer Developers, First, I am new to using Freesurfer, so I apologize if any information is unclear. I am attempting to use the following tutorial https://secure-web.cisco.com/1KKgvfrXJGjQJ5zjq_uJgVI7FZF_1Yms747_s_N5YKZgNC… to do a surface based GLM in an individual subject (using my own data, not the tutorial data), but I am getting the following error: Error using MRIread (line 76) ERROR: cannot determine format of /subnum/bold/runnum/masks/fmcpr.brainmask.fsaverage.lh (MRIread) I am getting that error because the fmcpr.brainmask.fsaverage.lh does not exist. To fix this error, I re-ran preprocessing using the following tutorial: https://secure-web.cisco.com/1R3ca-_kZlKG6UMHW-K0XesdEmNb2A3RSqg26YdNzjZ-Rh… After preprocessing, I still got the same error. Here are the files that do exist in that path: subnum/bold/run-num/masks brain.e3.nii.gz brain.fsaverage.lh.pr.nii.gz brain.fsaverage.rh.pr.nii.gz brain.mni305.2mm.pr.nii.gz brain.nii.gz.mkbrainmask.log brain.fsaverage.lh.nii.gz brain.fsaverage.rh.nii.gz brain.mni305.2mm.nii.gz brain.nii.gz There are some fmcpr files in this folder: subnum/bold/run-num fmcpr.brainmask.norm.2x2x2.nii.gz fmcpr.mcdat fmcpr.norm.nii.gz fmcpr.sm5.fsaverage.rh.nii.gz fmcpr.brainmask.normtmp.2x2x2.nii.gz fmcpr.nii.gz fmcpr.sm0.norm.nii.gz fmcpr.sm5.mni305.2mm.nii.gz fmcpr.mat.aff12.1D fmcpr.nii.gz.mclog fmcpr.sm5.fsaverage.lh.nii.gz fmcpr.sm5.norm.nii.gz Here are the commands I am running: These commands work: mkanalysis-sess -fsd bold -rlf $analysis_stem-$run_set.rlf -surface fsaverage $hemi -event-related -paradigm $PARA_NAME -refeventdur 18 -nconditions $nconditions -mask $func_stem.brainmask -gammafit 2.25 1.25 -nuisreg mcprextreg 6 -TR 1.0000 -polyfit 1 -analysis $analysis_stem-$run_set-$func_stem-$tpe.sm5.$hemi.$REG_STEM -tpexclude $tpe$TPE_STEM -funcstem $func_stem.sm$kernel$REG_STEM -per-run mkcontrast-sess -analysis $analysis_stem-$run_set-$func_stem-$tpe.sm5.$hemi.$REG_STEM -contrast Con1-Con2 -a 1 -c 2 preproc-sess -fsd bold -rlf $analysis_stem-$run_set.rlf -surface fsaverage lhrh -mni305 -fwhm 5 -per-run This command errors mkanalysis-sess -fsd bold -rlf $analysis_stem-$run_set.rlf -surface fsaverage $hemi -event-related -paradigm $PARA_NAME -refeventdur 18 -nconditions $nconditions -gammafit 2.25 1.25 -nuisreg mcprextreg 6 -TR 1.0000 -polyfit 1 -analysis $analysis_stem-$run_set-$func_stem-$tpe.sm5.$hemi.$REG_STEM -tpexclude $tpe$TPE_STEM -funcstem $func_stem.sm$kernel$REG_STEM -per-run 1.

interhemispheric registration: xhemi vs. mris_left_right_register
by Dr. Cornelius Kronlage 28 Nov '21

28 Nov '21

External Email - Use Caution Dear freesurfer community, concerning interhemispheric registration: What are differences between mris_left_right_register and the xhemi pipeline (including the fsaverage_sym subject)? I understand that xhemi/fsaverage_sym are meant to provide an unbiased reference as opposed to simply mapping all data to one hemisphere. I am trying to map a label from one hemisphere to the other on individual subjects. I noticed that mris_left_right_register results in output quite different from using fsaverage_sym via the xhemi process as an intermediate. As an example, see the figure file attached (original label on rh, mapped labels on lh). At the first glance, the output of mris_left_right_register seems to align with the curvature a lot better... For reference, the following code was used. Is that correct? surfreg --s ${subject} --t fsaverage_sym surfreg --s ${subject} --t fsaverage_sym --lh --xhemi mris_apply_reg \ --src-label rh.label --trg rh_on_lh.xhemi.label \ --streg ${SUBJECTS_DIR}/${subject}/xhemi/surf/lh.fsaverage_sym.sphere.reg ${SUBJECTS_DIR}/${subject}/surf/lh.fsaverage_sym.sphere.reg mris_left_right_register \ ${SUBJECTS_DIR}/${subject}/surf/lh.sphere \ ${SUBJECTS_DIR}/${subject}/surf/rh.sphere \ ${SUBJECTS_DIR}/${subject}/surf/lh.sphere.left_right \ ${SUBJECTS_DIR}/${subject}/surf/rh.sphere.left_right mris_apply_reg \ --src-label rh.label --trg rh_on_lh.left_right.label \ --streg ${SUBJECTS_DIR}/${subject}/surf/rh.sphere.left_right ${SUBJECTS_DIR}/${subject}/surf/lh.sphere.left_right Thank you and with best wishes Cornelius
