The examples directory of the distribution contains a set of instrument examples. These are used for the McStas self test procedure, which is executed with
mcrun --test
This test takes a few minutes to complete, and ends with a short report on the installation itself, the simulation accuracy and the plotter check.
You should now be able to use McStas. For some examples to try, see the examples/ directory. Start 'mcgui' (mcgui.pl on Windows), and select one of the examples in the 'Neutron Sites' menu.
Important note for Windows users: It is a known problem that some of the McStas tools do not support filenames / directories with spaces. We are working on a more general approach to this problem, which will hopefully be solved in the next release.
