It sounds great!
Thank you very much, Elaine!
Cheers,

> The other method (open with "coordset true" to make a trajectory) may be more difficult, in my opinion, and does not solve your problem of variable number of frames or models. You would still have to know that number and put it into the script in a "perframe" command. You would have to use "perframe" with "coordset" to play the trajectory and "hbonds" to calculate the H-bonds all in a single command line separated with semicolons (;), similar to what Eric described in this previous post, except with "hbonds" command instead of "2dlabel" command:

In ChimeraX the command is "hbonds" and you can specify the docked ligand model(s) directly, e.g. if they are all in #2, "hbonds #2 restrict any reveal true saveFile myoutputfile.txt" -- but please read the help to see what options you want:

Then when you click OK or Apply, the corresponding command will be shown in the Log. One difference, however, is that if using the GUI you would need to select the ligands first (which can be done with the Model panel checkboxes under the selecting-hand icon, or command like "select #2") whereas the "hbonds" command allows simply specifying them in the command, as in my example command above.
