Hello Everyone£¬<br> I‘m confused about Normal Mode Analysis of Gromacs. I have googled a lot but find little useful.<br> I installed Gromacs 4.5.5 by CMake on Win7(Double Precision).<br> Gromacs manual said "It is imperative that you use the <code>-t</code> option to <code><a title="Documentation/Gromacs_Utilities/grompp" rel="internal" href="http://www.gromacs.org/Documentation/Gromacs_Utilities/grompp">grompp</a></code> when you create the <span class="highlight" style="background-color:yellow">normal</span> mode <a title="Documentation/File_Formats/Topology_(.tpr)_File" rel="internal" href="http://www.gromacs.org/Documentation/File_Formats/Topology_%28.tpr%29_File">run input file</a>, so that you read full precision binary coordinates and not the three-decimal <a title="Documentation/File_Formats/.gro_File" rel="internal" href="http://www.gromacs.org/Documentation/File_Formats/.gro_File">.gro</a> file." But I don't exactly what it means....<br>
Could anyone give me a step-by-step example?<br> <br> Thanks in advance.<br><br>shen <br>
