[gmx-users] what's the meaning of g_msd's -trestart

[杜波]

dear teacher,
i read the groace_manual-4.5.4:
i found "The time between the reference points for the MSD calculation is
set with -trestart."
and "the defaut is 10ps."
do it computer the "msd" like this :
0ns compared with "-beginfit to -endfit "
10ns compared with "-beginfit to -endfit "
20ns compared with "-beginfit to -endfit "
30ns compared with "-beginfit to -endfit "
....
thanks!!!
