Hi, I would assume that any version of Debian or derivatives should be fine, as the NeuroDebian repository will take care of any updates automatically. Besides, installation of FSL is a breeze. Personally, I've been using Ubuntu (since its very first beginnings) and am still loving it. But this is my 2c. See neuro.debian.net for more details...!

The FSL website says you should use Red Hat 7,8,9 but I was informed that it no longer exists. I have Red Hat Enterprise 5.5 and I was wondering what I should upgrade to. Any help would be greatly appreciated. > > Best, > Dave
