<DIV class=RTE> </DIV>I have finished dynamics simulation of RNA using gromacs force field. when i analyse the results,i fould the .trr file is very huge (<STRONG>5.3G</STRONG>).So,i use the command "trjconv" to compress the file in order to minimize the space of the disk.
<DIV></DIV>
<DIV></DIV><STRONG>[root@localhost root]# trjconv -f 2_md.trr -o 2_md.xtc </STRONG>
<DIV></DIV>
<DIV></DIV>
<P>but when i hit the enter, there are "fatal error"as follows: </P>
<DIV></DIV><STRONG>Will write xtc:compressed trajectory(portable xdr format) </STRONG>
<DIV></DIV>
<P><STRONG>Fatal error :File 2_md.trr not found.</STRONG></P>
<P>next,i use the linux command "ls" looking for 2_md.trr in root directory:</P>
<P><STRONG>[root@localhost root]#ls</STRONG></P>
<P>To my surprise,there is 2_md.trr file in root directory!! </P>
<P>I want to know what happen to this and how to solve this problem.</P>
<P>(I process this dynamic simulation using a single computer with 256M memory,1.7G CPU and 40G disk space)</P>
<P>Thanks in advance! </P>
