function : Perform CoCo Analysis on the output of the simulation from
the current iteration. Using the .xtc files generated in all instances,
generate .gro files (as many as the num_CUs) to be used in the next
simulations.
coco :-
Purpose : Runs CoCo analysis on a set of MD trajectory files
in this case xtc files and generates several
coordinates file to be used in next cycle
Arguments : --grid = Number of points along each dimension
of the CoCo histogram
--dims = The number of projections to
consider from the input pcz file
--frontpoints = Number of CUs
--topfile = Topology filename
--mdfile = MD Input filename
--output = Output filename
--cycle = Current iteration number
--atom_selection = Selection of the biological part of
the system we want to consider for
analysis
