Hi, Indeed it's possible that the core algorithms for those programs didn't change too much between 3.2 and 3.3. Likewise for 4, except for FDT which will have a major upgrade to allow crossing fibre modelling for diffusion data. However, if you really need the old sources you could email me directly and I can give you a link to them - though if you currently have 3.2 then that will include all the sources, even if it was a binary download! Though you may have problems compiling very old code with very new gcc, wherever you get 3.2 sources from. Cheers, Steve.
