Dear experts<br>
<br>
I have a protein simulation in a water box. I now want to write a trajectory containing only the protein, and water molecules within 5 Angstroms of the protein, with the water list being updated each time step. How can one do this? Appreciate the help<br>

g_select is useful for "dynamic" selections of this type. g_select -select "help" can give examples and such.<br>
<br>
I'd hope it's been designed so that then using trjconv to extract such selections works, but I can't think how, having not ever tried.<br></blockquote></div><div>g_select writes out one index group per time frame. But trjconv can't use a different index group for each frame. Thus it can't be used to write out a trajectory with those atoms for each frame. Part of the problem is that the trajectory format doesn't support different number of atoms for different frames. </div>
<div>What is possible is writing a small script around trjconv to produce one gro/trr file per frame with only those atoms.</div><div><br></div><font color="#888888"><div>Roland</div></font><div class="im"><div><br></div>
