do you mean the msdND subfolder? It doesn't compile for me, while msd, msd2D, msd3D do....
I mean the change with a single msd.h file for all dimensions that allows n dimensions implementation. For each ND you want to use you have to compile a different object. It is explained in the build.txt of the msdND subdirectory.
Oh sure, that was actually my idea ;-) I thought you have introduced a dynamic version in the meantime... but that wouldn't make much sense anyway.
all the best, Thomas
