Or if you means specifically you want to measure cortical thickness from mri you could look into Freesurfer (

I want to perform cortical thickness analysis on a closed surface, isn’t this possible in the slicer at all?

Can you be more specific about what you need and why freesurfer doesn’t already do it? Slicer does a lot of things but we try not to duplicate tools that already exist.

I need to do thickness analyzing in slicer, freesurfer is only on mac and linux which I don’t have and also is huge(4.4-4.6GB) so I would rather to do this with slicer

Sorry, I don’t think there’s any easy way to do that.

  • run in a virtual machine (VirtualBox is free; I think VMWare Player or current equivalent is also still free and has better graphics performance)
  • if you have up-to-date Windows 10, you may be able to run under Windows Subsystem for Linux; someone posted instructions here:

(the second option will probably be faster and use less memory, but will have somewhat lower i/o performance and possibly unknown bugs if you hit unsupported syscalls)
