Hi,
Using the colvars module you can write a portion of the coordinates more
frequently than DCDfreq. (I did this for two atoms, for more it probably
gets cumbersome).
Another option is to run the simulation in small chunks with a high DCDfreq
and then only extract the desired selection using catDCD after each chunk
is completed. (This will probably be faster than a lot of colvars)
Best regads,
Ajasja
