python fslinstaller.py


FSL installer version: 3.5.7

Hi @Chandra_Park, how long have you been waiting for? The final step can take some time on systems with anti-virus software.

Thanks for your reply @paulmccarthy. I probably have been waiting for a least several hours. I tried deleting and reinstalling it a couple of times but the same problem persists. I don’t have any anti-virus software running that I am aware of. I’m on MacOS if that is helpful.

Would you be able to run the installer script with the --debug option, e.g.:

python fslinstaller.py --debug

And let it run until it reaches 100% at the Installing FSL into ... step, then wait another 10 minutes, and then share the installer log file? The installer prints the path to the log file when it begins.

How would I be able to share the installer log file? I’m just a high school student, so I’m a beginner to this whole thing. Thanks.

I’m guessing it’s too large to add as an attachment here. You could use any file sharing service of your choice, such as dropbox, google drive, etc. If you don’t have access to such a service, I can arrange a place to which you will be able to upload the file.

If you can arrange a method in which I can do that it would be so great.

Having the same issue on Windows using the WSL option, been stuck at 100% at the “Installing FSL into…” step for 4 hours.

Hi @Nima_Hadidi, would you be able to run the installer with the --debug option as I suggested above, and share the log file? If you are unable to share the file via e.g. dropbox, then I will need your email address in order to set up a shared folder via my university’s sharepoint (I’m still waiting for Chandra to get back to me on that).
