Re: [Freesurfer] Freesurfer Digest, Vol 232, Issue 12 - data not displayed

External Email - Use Caution Thanks Bruce, Changing the coordinates still left me with a blank screen, but I tried using glxgears to further troubleshoot and that also resulted in a blank black screen. I was able to fix this by disabling my graphics card (Intel Iris XE). While this enabled freesurfer then to display the mri data, I discovered that I am not able to click on anything within the voxel edit or recon edit pop-up menus (like in this post: Re: [Freesurfer] Freeview Edit options restricted (mail-archive.com)<https://secure-web.cisco.com/1mhxyoaRo0TPOzY61gZ72Ihv17F6eoLxQkrIKSVeF9WmwB…>) and I wonder if this may be related to my graphics card?

External Email - Use Caution glxgears not displaying anything is usually an indication something is wrong with the X windows connection/setup, i.e., nothing displayed or black screen.  WSL and configuring an X-server is a moving target, and MS changed how this works with WSL2 compared to WSL1.   We have some notes on the setup with Xming under 'surfer.nmr.mgh.harvard.edu/fswiki/FS7_wsl’ which might help if you have not already seen them.  I have not run into a case where images work but mouse events do not, however there are postings about this, 'stackoverflow.com/questions/62203272/how-to-fix-nonfunctional-x11-mouse-on-…' As Ruopeng mentioned, you might want to try configuring MobaXterm instead of XMing,   'mobaxterm.mobatek.net/download.html’. Some users avoid the above by using our Ubuntu 18 VM image hosted by Virtualbox on Windows since the OS running in the VM uses its own built-in X-server.  The FS 7.2.0 release is already installed and tested in that Ubuntu OS image and it should work to upgrade the OS and/or change the FS release on it as you like,  'surfer.nmr.mgh.harvard.edu/fswiki/VM_67' - R.

recon-all-clinical problems
by Michael Mc Laughlin 23 Jun '23

23 Jun '23

External Email - Use Caution I tried recon-all-clinical and there are two main problems 1) I ran it on a T1-MPRAGE image and it looks fine except that there are no lateral ventricles in the output. See attached. 2) I get lots of errors at the end. I read the following note in the release notes: *Please replace $FREESURFER_HOME/bin/recon-all-clinical.sh with the latest version HERE <https://secure-web.cisco.com/1by8vHZBkgali1lqEExldl9RRMDAvkcckApenn9NS-6rjg…>. Development versions newer than June 15th 2023 do not have this problem.]* I am not a linux expert, so I don't know how to download that file. If I could download it I am sure I could manage to replace it in the bin directory. I made an attempt by clicking on the link and copying the text from my browser into a new text file. I used this to replace the supplied file, but I still get errors. Maybe I screwed up. Michael McLaughlin, Island View, Beulah Court, Harbour Road, Dalkey Co. Dublin Ph:+353 87 688 2514

Freesurfer installation help
by Michael Mc Laughlin 23 Jun '23

23 Jun '23

External Email - Use Caution You seriously need to improve the installation help for non-linux experts. I spent six hours trying to upgrade from 7.3.2 to 7.4.1. The first 40 minutes was going through your help pages and reading very carefully starting here: https://secure-web.cisco.com/19ID4blh6dH7zLY1eBU3QOvif6gsUtz6XQjFV1RthoGhJD… and here: https://secure-web.cisco.com/1G2hfa6Pr6IRUiy_FTikis58foj-czVVon8c5s59_Asqy8… and many other linked pages Only to find that there are not actually any instructions on what to do. All you needed to say was: *Find out what version of Linux you have with the command:* cat /etc/os-release *Download the appropriate file e.g. for Ubuntu 22 use the Deb installation file* freesurfer_ubuntu22-7.4.1_amd64.deb <https://secure-web.cisco.com/1-yCca0DS1VPostBIzb--8M5elp1jaN909370VQ3Cl48vQ…> *Then, for Ubuntu, install with the command* sudo dpkg --install <filename> That would have saved me 6 hours! I don't know linux so I don't know these basic commands. A big problem for me was that I didn't know what version of Ubuntu I had but I didn't know that I didn't know that and none of the installation tools I tried told me, they just gave me unintelligible errors. I think that because you are all linux fluent you have blind spots about some of this basic stuff. Michael McLaughlin,

GM Threshold too low
by Michael Mc Laughlin 21 Jun '23

21 Jun '23

External Email - Use Caution How can I set the threshold used for Gray matter? I have a T1 mprage scan and a large amount of gray matter is clearly not being included (see attached). There is a lot of help on setting the GM/WM threshold but I can't find anything about setting the GM/CSF threshold. [image: image.png]
