<DIV>&nbsp;Hi all</DIV>
<P>I downloaded topolbuild1_3 from the GROMACS website,</P>
<P>and I run the command as follows:</P>
<P>````````````````````````````````````````````</P>
<P>"path: home/buct/topolbuild1_3&nbsp;Ħħ</P>
<P># tar -xvf topolbuild1_3.tgz</P>
<P>#make -f Makefile&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;;&nbsp;&nbsp; (intel CPU)&nbsp;there were no any&nbsp; error messages.</P>
<P>then I write "export PATH=$PATH:/home/buct/topolbuild1_3 "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;into etc/profile(root)</P>
<P>```````````````````````````````````````````</P>
<P>But When I&nbsp;type "topolbuild -h" I get "command not found",and I don't know how to deal it.</P>
<P>can anyone tell&nbsp;me to install the topolbuild1_3 correctly? </P>
<P>&nbsp;Thank you!</P>
