I'm trying to install JIST on an ubuntu machine, but I'm not even quite sure of what JIST is/does.

I've installed it as a plugin for MIPAV, but I was instructed to install it also as a standalone. My problem is I'm not really familiar at all with any of this software and it's unclear to me what's what. On the downloads page I see mostly stuff which is marked as MIPAV bundles, which is what I set up as a plugin. But then there's the JIST 2.0 stuff which I guess is probably the standalone, but it's from 2010.. is that normal? I tried downloading it but when I try to execute the .jar file it says its not an executable and is "not marked as executable" and something about executable bits.

If anyone can point me in the right direction it would be greatly appreciated.

Sorry for my ignorance, I'm just a research assistant newbie with limited linux experience and essentially zero neuro/image experience.
