HCP-MMP1 Parcellation to individual brain for stats
by Alina Rojas 20 Jul '20

20 Jul '20

External Email - Use Caution Hello Freesurfer support list, I’m attempting to map the HCP-MMP1-Atlas to the individual brains of my subjects to get the values of the parcellation, like aparc.stats but aparc being HCP-MMP1. The aim ist to compare the cortical thickness of the Parcellation given by the HCP-MMP1-Atlas between subjects. I searched the archive and didn’t find the solution. It would be so great if you could help me! Thank you and regards, Alina Rojas

Error for version 7.1.0 when run the recon-all
by Yang Molly 20 Jul '20

20 Jul '20

External Email - Use Caution Hi list, I tried to run the latest version Freesurfer (7.1.0) on the Ubantu 18.04 system. I downloaded the “freesurfer-linux-centos7_x86_64-7.1.0.tar.gz” and successfully installed. I tried to run "recon-all -s bert -autorecon1" and the terminal replied as "recon-all -s bert finished without error ". However, when I tried to run the recon-all use the common" recon-all -i /home/molly/FStry/preA063/preA063.nii -s sub063 -all", the terminal replied "Traceback (most recent call last): File "/usr/local/freesurfer/python/scripts/rca-config", line 137, in <module> file.write(arg + '\n') UnicodeEncodeError: 'ascii' codec can't encode character '\udc87' in position 12: ordinal not in range(128) ERROR: could not configure recon-all parameters" I did not retrieve a similar question in the previous mailing list and hope to get your help. Thank you Molly

Re: [Freesurfer] T2 or FLAIR data to improve pial surfaces

External Email - Use Caution What is the resolution of these images? Matt. From: <freesurfer-bounces(a)nmr.mgh.harvard.edu> on behalf of "Batra, Vinita R." <vbatra(a)lsuhsc.edu> Reply-To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Date: Monday, July 20, 2020 at 11:13 AM To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] T2 or FLAIR data to improve pial surfaces External Email - Use Caution Dear FreeSurfer experts, I have both T2 and FLAIR images for the majority of the subjects in my study, and I want to use them to improve pial surface reconstruction during recon-all as explained in [1]. My questions are: 1) In general, should I prefer FLAIR over T2, or the other way around? 2) Some subjects (< 10%) do not have a FLAIR image, and others do not have a T2. Do you think that it is fine to use FLAIR for some subjects, and T2 for others, in the same study? We will perform manual QC after the recon-all run and exclude bad quality images so I wanted to hear your opinion.

PetSurfer Crashing
by Crawford, Anna 20 Jul '20

External Email - Use Caution Hello, I am trying to run the PetSurfer process for the first time. I was able to run gtmseg and mri_coreg which seemed to go okay.

Right and left on MRI scan and on images
by Cibele Bandeira 20 Jul '20

20 Jul '20

External Email - Use Caution Hello, I have an MRI sample collected on a Siemens Magnetom Spectra 3T scanner. However, we do not place any pointing devices inside the scanner to indicate which side is the right and which is the left. I was wondering how the images were acquired - from the front of the individuals, meaning that the left in the image is the right in the patient? Or otherwise? When processing the T1-weighted images on Freesurfer, I also have a doubt... the DICOM images are synchronized? Left in DICOM is left in the patient? And after freesurfer preprocessing? It flips the images or not? Thank you very much! -- *Cibele Edom Bandeira* Doutoranda em Genética e Biologia Molecular (PPGBM) Universidade Federal do Rio Grande do Sul (UFRGS)

Converting volume to icosahedron surface
by Tse, Teresa 18 Jul '20

18 Jul '20

External Email - Use Caution Hi all, I am trying to convert a volume file (fMRI data in nifti format) into an icosahedron (4th order) surface using Freesurfer's mri_vol2surf command. I have been using nipype as a wrapper for Freesurfer and the other packages that I need for my processing. The command that nipype ran is: mri_vol2surf --hemi lh --icoorder 4 --o /dev/shm/RT_processing/_hemi_lh/to_surface/lh.003-FunctionalCMRR-2mm69sl1p5s_mcf.mgz --reg /dev/shm/RT_processing/convert_xfm/InplanetoAnatomy.xfm --projfrac-avg 0.000 1.000 0.100 --mov /dev/shm/RT_processing/motion_correction/003-FunctionalCMRR-2mm69sl1p5s_mcf.nii.gz --trgsubject ico The output of this command is a mgz file (attached to this email). I was unable to view this mgz file using Freeview's "Load surface" (I get the error "freadFloat: fread failed"). I was able to load the mgz file into Matlab using the load_mgh function. It loaded as a 2562 length vector (consistent with the number of vertices of a ico-4 surface). I have several questions regarding the output of the mri_vol2surf command that was run. 1) I am unsure as to whether the command that was used is correct, and whether the output mgz file that I got is the correct or expected output. What do the values of the vector represent? 2) Do you know how to load and view the output mgz file in Freeview? Is it supposed to be an overlay or annotation to an ico-4 surface file? If so, where would I find this ico-4 surface? 3) How do I find documentation and information about the icosahedron surface in Freesurfer? Many thanks, Teresa

Re: [Freesurfer] freeview 3.0
by fsbuild 17 Jul '20

17 Jul '20

External Email - Use Caution I don’t see freeview directly linking against libXm.so from Motif, though it does link against X windows libraries like libXmu.so and libX11.so.  You can see this with the “ldd” command  (some examples in screenshot below).   I don't think the RPM installer for freesurfer installs any Motif libraries.  I don't have any Motif libraries installed on my CentOS 7.7 image running under WSL that runs freeview/freesurfer. Now it could be you installed some packages on your system that installed Motif and/or also maybe changed the X windows distribution libraries (as used by freeview). - R..
