how to define the numsteps in ABF or metadynamics simulation?

Hi, everyone!

 I want to calculate the PMF along a colvar (distance), then I tried to perform an ABF and metadynamics simulation. But I am not sure how to define the numsteps in the ABF.conf file? How many MD steps should I carry out enough to get reasonable PMF? Is there any rules to calculate the parameter - "numsteps"? how many should this parameter("numsteps") be at least?

   Thank you very much!

     

cheers
