I would like to use catdcd to write POPC trajectory from water, following
the example from the download website:

catdcd -o eq_pro.dcd -i protein.ind eq01.dcd

        Takes only the coordinates corresponding to the indices in
        'protein.ind' from eq01.dcd and writes them to eq_pro.dcd

I supposed I will need an .ind file for my POPC. How will I create that?

Thank you,
