# COLVAR output of a restarting job of metadynamics

Hi

If MTD is running, the columns from 4 to 9 should not be zero.
Since you use two CVs, the columns in the *COLVAR* file are
Time    CV1    CV2    MTD_Force on CV1       MTD_F on CV2      WallPot_F on
CV1        WallPot_F on CV2    MTDPot       WallPot

where the forces and the potentials are intended at the actual position in
the phase space where the trajectory is at that specific time,
hence, considering the number of MTD hills already spawned.

Regards
Marcella
