External Email - Use Caution Let me just add, the tar archive listed in your email, freesurfer-linux-ubuntu20_x86_64-7-dev.tar.gz, is the install image (and not the source code) from a *development* nightly build on Ubuntu 20 which has not been tested like a freesurfer release.    So if you are looking to start using freesurfer commands and binaries that are already built and organized as a distribution (from either the tar file or the installer files), then you should consider using the existing, stable 7.2.0 release (which you can get from https://secure-web.cisco.com/1_rhmCsv6clReJC6U3u5VnsAa0yDplUEXxuv…)  The 7.2.0 release does have Ubuntu 18 binaries and an installer available via the link above.  I believe those binaries should run on Ubuntu 20. Installed images of freesurfer (including Ubuntu 18 binaries) are available in various system images  including a container, a VM, and also you can run it under the Windows Subsystem for Linux (WSL).  We have some info about that here if you just want to get started trying the commands, https://secure-web.cisco.com/1IqL_pExkd0h4Ll0hp7UdgBqalAfNpw… - R.

FreeSurfer Course
by Kretzer, Svenja 26 May '22

26 May '22

External Email - Use Caution Dear all, I hope you are well. I am a PhD student studying neuroscience at King’s College London. My project is on adolescent neurodevelopmental growth trajectories and internalising symptoms. I’m using FreeSurfer and I believe I’d highly benefit from the course offered on your website. I was wondering whether you are offering a course September this year. Could you please let me know if there is one and if so, if you have spots available? Thank you very much, I look forward to hearing from you! All the best, Svenja

using freeview7 to set manual paths
by Valeria Centanino 26 May '22

26 May '22

External Email - Use Caution Hello, I need to set manual paths on inflated surfaces, and I would like to use FreeView7, but I couldn't find any option to save the path after creating it. Could you please tell me if this is implemented in FreeView7 and, if yes, how can I do it? Thanks very much, Valeria

mris_label2annotation issues with individualizing
by Deck,Benjamin 25 May '22

25 May '22

External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to create annotation files from label files which have been estimated at the level of the individual. Therefore, some subjects may not have all ROIs. When attempting to take those label files and concatenate them into individual subject-specific annotation files I run into a few issues. The command I have used previously: mris_label2annot --s sub-DAEK --hemi lh \ --ctab /mnt/c/Users/Ben/Documents/GitHub/parcellationPipeline/li2019_to_dti/yeo2011nodesLUT.txt \ --a yeo2011nodes \ --surf orig \ --maxstatwinner \ --ldir-default stdout: subject sub-DAEK hemi lh SUBJECTS_DIR /mnt/c/Users/Ben/freesurfer/subjects ColorTable /mnt/c/Users/Ben/Documents/GitHub/parcellationPipeline/li2019_to_dti/yeo2011nodesLUT.txt AnnotName yeo2011nodes nlables 0 1. The first issue is that -ldir and -ldir-default don't seem to work as anticipated. After reading many threads on the FS mailing list archives I saw that the LUT should have identical ROI IDs as the file names with the exception of the label file extension. Thus, my LUT looks like the following: * 0 Unknown 0 0 0 0 1 lh.Net_2_ROIs_1_lh 25 5 25 0 2 rh.Net_2_ROIs_1_rh 25 100 40 0 3 lh.Net_2_ROIs_2_lh 70 130 180 0 4 rh.Net_2_ROIs_2_rh 100 100 0 0 5 lh.Net_3_ROIs_1_lh 196 58 250 0 6 rh.Net_3_ROIs_1_rh 100 25 0 0 7 lh.Net_3_ROIs_2_lh 120 70 50 0 8 rh.Net_3_ROIs_2_rh 220 20 10 0 9 lh.Net_3_ROIs_3_lh 220 20 100 0 10 rh.Net_3_ROIs_3_rh 180 40 120 0 11 lh.Net_4_ROIs_1_lh 122 186 220 0 -----------------and so on. * When I list the dir from my subject's label directory the following is presented: i. lh.Net_10_ROIs_1_lh.label lh.Net_2_ROIs_1_lh.label lh.Net_13_ROIs_3_lh.label lh.Net_5_ROIs_1_lh.label rh.Net_2_ROIs_1_rh.label rh.Net_3_ROIs_3_rh.label ------------and so on. * However, when I provide the -l arg with the full path, the file is found and the nlabels arg in stdout is the number of -l args I supply. 1. The next issues is that if I go the route of -l args (there are 116 ROIs so this is not desirable) I receive issues because not all subjects have all the label files that the LUT file expects. Therefore the resulting annotation file has mislabeled ROIs. * Is there a way to force the unfound labels to unknown or a way to bypass this issue? * I recognize the one way to do this may be to create individual specific LUT files but that seems tedious and unnecessary if there is a better way that you all may be wiser to. 1. Another issue I have been running into is that if I even attempt to just remove the -l args where labels do not correspond exactly with the LUT file I have a number of overlapping label file vertices issues. * How do you recommend correcting for this, my best guess is some sort of thresholding scheme. However, these are functional networks so I am unsure what the best route for thresholding would be. Thanks so much for your help in advance! Ben

Deface DICOM
by Victor Montal Blancafort 24 May '22

24 May '22

External Email - Use Caution Dear FS experts, I am using mri_deface to annon our data. Nevertheless, for a recent project, we were requested to share our DICOM original files, instad of .nii or .mgz. Thus, I was wondering if you know a simple way to deface T1 data inputing a DICOM and obtaining a series of DICOM as output? I have tried to 1) deface using mri_deface, 2) convert the .nii to dicom using the nifti2dicom utility and 3) correct DICOM info thats incorrecly parsed at step 2). However, such approach does not work correctly for all our data (it fails for several reasons, such as correctly storing acq direction, or dimensions when sampling from nifti 2 dicom). I have seen that @Doug has been working on a new deface utility (mideface) but it seems to work also only for .nii Any insight? Victor Montal

Tissue fraction effects correction
by Marina Fernández 24 May '22

24 May '22

External Email - Use Caution Dear FS experts, We are planning to correct for tissue fraction effects on T1w/T2w ratio images using PETsurfer, setting the point spread function estimate to zero. My questions are: 1. Does it make sense to correct for tissue fraction effects on T1w/T2w ratio images even when T1w and T2w images were acquired using the same matrix size with identical voxel resolution (i.e., 1mm3)? 2. If that makes sense, which PVC method would work best for correcting tissue fraction effects (i.e., SGTM, MG, RBV) on structural MRI scans? Many thanks in advance. Best, Marina
