Re: [Freesurfer] mri_easyreg tool
by Iglesias Gonzalez, Juan E. 22 Feb '23

Sorry for the late response, I went on vacation the very same day you posted your question. The floating image is the one you want to deform, and the reference image is the one you use as target for the registration /deformation. In other words: the deformed floating image should overlap with the reference image. More information here: https://surfer.nmr.mgh.harvard.edu/fswiki/EasyReg Kind regards, /Eugenio -- Juan Eugenio Iglesias http://www.jeiglesias.com From: <freesurfer-bounces(a)nmr.mgh.harvard.edu> on behalf of "Peters, Johnny Y" <jonathan-peters(a)uiowa.edu> Reply-To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Date: Friday, February 10, 2023 at 11:40 To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] mri_easyreg tool External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to use the mri_easyreg on the developmental version of freesurfer but I am confused about what .mgz or .nii(.gz) I am supposed to use for the reference image, floating image, and the others. I saw no previous threads on the mailing list addressing my question so I decided to email you. Would you be able to give an example command line using the subject bert in the freesurfer directory? Thank You

Correlating and/or linear regressing surface overlays
by Finn, Quentin 22 Feb '23

22 Feb '23

External Email - Use Caution Freesurfer experts, I have some surface data that I'd like to correlate with some other data, although a linear regression would also be fine if I could get something like a t-stat out of it. This data came from two different PET tracers -- voxelwise data was resampled via vol2surf onto each subjects cortical surface: So I have, say, data like this: tracer1_subj1_lh.mgh tracer1_subj2_lh.mgh . . . . tracer1_subjn_lh.mgh And then I have another set: tracer2_subj1_lh.mgh tracer2_subj2_lh.mgh . . . . tracer2_subjn_lh.mgh I'd really like to just stack them all up with mris_preproc, something like this: mris_preproc --is tracer1_subj1_lh.mgh --is tracer1_subj2_lh.mgh [etc] --is tracer1_subjn_lh.mgh --out tracer1_lh.mgh --hemi lh --fsgd tracer1.fsgd mris_preproc --is tracer2_subj1_lh.mgh --is tracer2_subj2_lh.mgh [etc] --is tracer2_subjn_lh.mgh --out tracer2_lh.mgh --hemi lh --fsgd tracer1.fsgd The FSGD's are the same because the subjects are the same. and then run something like... mri_glmfit --glmdir tracer1_tracer2_left --y tracer1_lh.mgh --fsgd tracer1.fsgd --pvr tracer2.mgh --no-contrasts-ok --surface fsaverage lh This doesn't have an output that's really what I'm looking for as far as I can tell though, there's no fit statistics type overlay in the output folder, probably because I'm doing something wrong. Any help on this would be just wonderful! -quentin finn Houston Methodist. Leading Medicine.

Nuisance regressors
by Marilena Wilding 22 Feb '23

22 Feb '23

External Email - Use Caution Hi Freesurfers! I would like to compare the effect of different nuisance regressors (I.e., cardiac and respiratory signal, motion) on my resting-state data. For that I’m adding the respective regressors to my first-level GLM. Now, how can I best compute a contrast between the effect of different physiological regressors and motion? Would I add them as task regressors in 1st level or rather as nuisance regressors and how can I get second-level comparison of their effect? Thanks in advance for your help! Best, Maria

External Email - Use Caution The best solution (which I think was previously emailed to you) is to have an admin/IT person update your system by doing the following: 1) Copy the link for the freesurfer release install package matching your Ubuntu system, e.g., 7.3.2 freesurfer release on Ubuntu 18, 20, 22, from https://secure-web.cisco.com/1yhwT1AT1siR71m0xkciflHcVEcWiQ2tB105s7o77YZsEO… 2) Download and install it with, $ wget <link copied from the web page above> .... say wget downloaded the file freesurfer_ubuntu18-7.3.2_amd64.deb  .... $ sudo apt-get install ./freesurfer_ubuntu18-7.3.2_amd64.deb That should install libncurses and anything else that's needed automatically.   Trying to piecemeal run commands to install individual system packages like libncurses is asking for more trouble. - R.

How to calculate the mean FA value in the hippocampus
by Lin Cai 22 Feb '23

22 Feb '23

External Email - Use Caution Dear Freesurfer experts, I want to calculate the mean FA value in the hippocampus. Now I have already obtained the FA map for the whole brain in the native space. And I have the aparc+aseg.mgz file after running the recon -all analysis. Does someone know how to use freesurfer functions to obtain the hippocampus mask according to the DK atlas? I want to use this mask to calculate the mean FA value in the hippocampus. Best regards, Lin
