Hi!
I am actually following your lysozyme tutorial. I ve been using different pdb files including that of water, methanol, 1AKI, etc. The pdb2gmx does not generate any topology file. No files are generated and I get this error: ------------------------------------------
pdb2gmx, VERSION 4.5.3
Source code file: futil.c, line:491
File input/output
1AKI.pdb
For more.... etc
------------------------------------------


Then this file doesn't exist in the working directory. What is the command you're issuing (exact copy and paste from the terminal, please)? What are the contents of the working directory?

        Typing an email and waiting for a response takes far more time
        and effort than simply trying it yourself ;)
