Need help regarding well tempered meta-dynamics in cp2k

[Kaustubh Pathak]

Hello, I am trying to break the methane molecule in the Mo2C+KCl molten system.

I have assigned two collective variables one C-H coordination number and other H-Surface atom coordination number. The metadynamics simulation is running but I am not able to interpret it. I am attaching the input and output metadynlog log please explain the output values and corresponding zeros. And for each step a new file is generated and I need one file like energies which store all step information.

Hello ?

To combine all mid output in single files please add the following print section to the mid section 

&PRINT &COLVAR COMMON_ITERATION_LEVELS 3 &EACH MD 1 &END EACH &END COLVAR &HILLS COMMON_ITERATION_LEVELS 3 &EACH MD 1 &END EACH &END HILLS &END PRINT

Further explanation of the input and output can be found ot

and

Thank you for the suggestion. Just one more doubt how to interpret the colvar  metadynlog file because it comes without and headers. And after this runs should I do anything else to ensure the methane breaks to CH3 and H.
