[CP2K:7095] Re: COLVAR output of a restarting job of metadynamics

[Guanna Li]

Marcellar, thank you for your explanations.
You point to a new question: I confirmed that my MTD was running smoothly
and I can view the reaction was "taking place" along the CVs.
Then the question would be: why I had zero for columns 4-9 in the first
step? I am wondering that maybe columns 4-9 are controlled by the PRINT
section and the default settings for them was "OFF"? However, i didn't find
any key words related to them in the manual.
