Hi Gmxers,

I used g_dist to find all water molecules within 5 Angstrom of a protein in a trajectory with a little surprise that gromacs directly prints out those water on my screen rather than in an output file.

According to g_dist -h, that's what you should expect :)

Since in each frame, those water molecules are not the same, I realize I need to make a dynamic index or indices for them. However I do not see any flag I could possibly introduce those water in g_select and then use -on flag to produce a dynamic index.

The index groups are output by g_select. Try g_select -select "help all" for examples of how to create groups.
