<br>nstvout = 0<br>nstfout = 0<br>; Checkpointing helps you continue after crashes<br>nstcheckpoint = 0<br>; Output frequency for energies to log file and energy file<br>nstlog = 1000
<br>nstenergy = 100<br>; Output frequency and precision for xtc file<br>nstxtcout = 10<br>xtc-precision = 1000<br><br><br><br><br><br><div><span class="gmail_quote">2007/11/1, David van der Spoel <
