macro filename {Filename (Run_Number)}
to
macro filename {File_Name (Run_Number)} |
This is getting the value from the File_Name list at index=Run_Number.

This macro uses multiple cutoffs and a sphere radius for a transition from correlated (low-r) to uncorrelated (high-r) motion. beqcut is the beq value to be used in the region between 0 and rcut. beqlo is the beq value to use in the region between rcut and rlo. beqhi is the beq value for the region r ≥ 2*radius + rlo |
