[gmx-users] luck

[Mr Bernard Ramos]

Hi everyone!
 
I have two questions.
 
1. after I installed gromacs 4.5.3 and "which mdrun" was able to give the correct path, I was not able to run "luck". Instead, "luck" gives an error "command not found". Is this ok? What went wrong? Do I need to install again gromacs?
 
2. I tried doing "pdb2gmx". The error points the structure file "*.pdb" as the error. Does this in dicate that the program was not installed properly or there is an error with the pdb file.
 
 
Thanks
