Hi, I am new to MRTrix3 and ran the Download and Installation instructions online. I redownloaded using the code form the instruction and was met with this: $ pkg=$(curl -s https://api.github.com/repos/MRtrix3/mrtrix3/releases/latest | grep browser_download_url.*.tar.xz | awk '{print $2}' | tr '"'…

Hi @Hunainabri , Can you provide more detail on your system and OS? Is this on Windows 10 or 11? Using the latest version of MSYS2? Run from the MinGW64 terminal? Using what hardware exactly? There is also an odd error message that I’ve not see before: warning: database file for 'clangarm64' does …

I am on Windows 10 using a x64-based processor. I believe I am using the latest MSYS2 and MinGW64 terminal as I followed the download instructions from MRTrix3 and MSYS webpage. How would I about checking that? Thanks! Hunain

OK, so that’s not the issue… To check whether you’re running in the right terminal, I think the simplest things is to type: echo $MSYSTEM Also, I’m not sure whether you’re getting a ‘command not found’ error, or just that mrview seems to hang. If you type mrinfo, do you see the help page for that…

[image] Here is a screenshot of everything you recommended to try. I have left the terminal open for hours after entering mrview, etc. and still nothing pops up. what would you recommend for the next steps? I also appreciate all the help! Hunain

Hi @Hunainabri , Just to confirm: typing mrinfo shows nothing at all? You should see the command help page, which you can navigate through and exit by typing q. If even that isn’t working, then the issue isn’t related to the GUI aspects. I’ve not come across anything like that before, my best guess…

Hi, After moving to a new freshly installed computer over the past days (Windows10.0.19044, x64 i7) I saw exactly the same behaviour after installing msys and mrtrix. No output at all for any mrtrix command. During the installation there was also the warning about the missing clangarm64. Apparently…

Ok, thanks for the report. I’ll investigate when I have a minute – it’s hopefully something simple… :crossed_fingers:

FYI. Building mrtrix from the sources worked fine. So I guess that might be a workaround for @Hunainabri as well…

Thanks! I will try that. could you further explain what you mean by sources? I am very new to this and still trying to get it to work :sweat_smile: Hunain

Just follow these instructions: Building MRtrix3 from source
