Hi, I am traveling and don't have time to answer this now, nor am I responsible for the tutorial you mention. I also only usually answer questions like this on the gromacs users list, not in my personal e-mail. I suggest you direct your e-mail to the Gromacs users list (which I am ccing on this)

Hi, While using trjconv and the like, it is possible to select multiple groups and write out their trajectory (for example, proteins AND ions) ? Or does one have to write a new index file to be able to do this ? Thank you very much, -Himanshu ___ gmx-
