I am using Mathematica version 10.1 and SpinDynamica version 2.13.1.
I encountered two problems while simulating a REDOR experiment (notebook attached) starting from REDOR example in (http://www.spindynamica.soton.ac.uk/usage/nmr-examples/
(1) For a single crystallite orientation, if I calculate REDOR trajectory of operators Iy and 2IxSz with an initial operator Iz, I do not see any evolution. Whereas, if I start the same calculation with an initial operator Iy, the result looks fine.
(2) When I try to calculate the powder averaged signal using EnsembleAveraging by TransformationAmplitudeTable, it produces errors.
It would be great if someone can help.
