the call to gtltcube_mp fails because too many arguments are given, this is because gtltcube_mp no longer has the arguments for tmin & tmax that it used to have (were both called as 0 in the original code).
soln. replace lines 184-5 with:
ltmp.gtltcube_mp(np, expCube['scfile'], expCube['evfile'], expCube['outfile'],
False,expCube['zmax'])
