assuming the order of the columns in your file is just: timestep, variable_of_interest, other stuff... then you don't need to do any extraction, just feed it the raw files.

I have .colvars.traj files and the output frequency is high enough (every 5ps). The easiest way for me would be to extract the information from .colvars.traj directly and apply them into WHAM by Grossfield.

Chris,

Thanks for your encouragement! I would like to try to write up such kind of code for learning purpose. For now, a well established software is more straight forward and safe for me. :-)

Thanks again!

Best regards,
Ada

Ada,

Do you not also have the .colvars.traj files?

I take Jerome's point about the discreet nature of the data, but if the frequency is far higher than the decorrelation time than it's mostly irrelevant.
