FSL (an fMRI processing and visualization tool) doesn't run on Windows 10 as a native app.
You'll need to install Xming: http://www.straightrunning.com/XmingNotes/ or another windowing app to use with FSL.
To install FSL do the following:
From Windows:
1) From the search bar, type: "Turn Windows Features On/Off".
2) Check off the box next to: "Windows Subsystem for Linux" .
3) Reboot.
4) From the Windows Store search for: "Ubuntu 16.04 LTS" (may work w/ 18.04 but did not test), and install (creating a username and password).
***
Optional:
5) Mount the file share you want to work with in Windows, e.g.: \\fmrilab.psych.nyu.edu\phelpslab\Linda , providing user credentials, and taking note of the assigned drive letter, e.g.: "P:"
***
From Ubuntu:
6) Update software: sudo apt-get update && apt-get upgrade -y .
***
Optional:
7) Install CIFS utilities: sudo apt-get install -y cifs-utils .
8) Create a mount point, e.g.: sudo mkdir /mnt/phelpslab .
9) Edit fstab so that the mount survives a reboot: sudo vi /etc/fstab
and include an entry for the share you want to mount, e.g.: P:/Linda /mnt/phelpslab drvfs defaults 0 0
10) Mount the share: sudo mount -a (confirm that you are able to access the share).
***
11) Register for the FSL download: https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FslInstallation , being sure to grab the Linux (not Windows) package installer.
12) Download the installer (it will download to C:\Users\username\Downloads in Windows).
13) Copy the installer to your present working directory in Ubuntu: cp -v /mnt/c/Users/username/Downloads/fslinstaller.py . (include the ".").
14) Install python: sudo apt-get install python -y
14) Run the installer (w/out sudo): python fslinstaller.py (provide sudo credentials when prompted)
15) Type: export Display = :0 (you can probably set this in .bashrc, but didn't test)
16) Type: fsl
FSL pops up. You can run it as a background process with: fsl & (this way you don't have to open up a new terminal).
