I am about to burst into tears now, since I am unable to get in touch with you guys. My problem is regarding the installation of gromacs 4.6.1, I followed exactly what was said in https://rohitnarurkar.wordpress.com/2013/08/26/gromacs-installation-for-linux-users/ I followed with success till the last one,but when I typed grompp, it showed error like Program grompp, VERSION 4.6.1 Source code file: /home/roshan2004/Downloads/gromacs-4.6.1/src/gmxlib/futil.c, line: 593
File input/output error: grompp.mdp For more information and tips for troubleshooting, please check the GROMACS website at http://www.gromacs.org/Documentation/Errors with some information about gromacs above, when I typed which mdrun Program mdrun, VERSION 4.6.1 Source code file: /home/roshan2004/Downloads/gromacs-4.6.1/src/gmxlib/gmxfio.c, line: 524
Can not open file: topol.tpr For more information and tips for troubleshooting, please check the GROMACS website at http://www.gromacs.org/Documentation/Errors So, clearly, there are some errors, Now, how to fix this ? **I even tried to install by using sudo apt-get install gromacs , but then when I typed mdrun, it gave same problem as above - Can not open file: topol.tpr ** Even after installing via sudo apt, it gave me following problem: /usr/bin/mdrun roshan2004@ubuntu:~$ mdrun GROMACS: gmx mdrun, VERSION 5.0.2
