Hi Jimmy, I hope the cold wasn't bad. For the problem you are seeing, scons is actually a separate software program and not part of relax. It should not be run inside relax but instead on the command line, powershell prompt, etc. by itself. But note that you probably never need to use it! If you run: $ relax --info and at the bottom you see: Compiled relax C modules: Relaxation curve fitting: True then you can forget about scons. Are you using the MS Windows 32-bit Zip archive of relax (relax-1.3.13.Win32.zip)? If you have used this Zip file and the relaxation curve fitting C module message says False, then we can start thinking about using scons to build these modules. But this is rarely the case.
