But every time it produces an output file, I get this error: "output.pdb2gmx: Permission denied.", so I can't view the output. I am also unable to locate the .trr file, which is supposed to be the ultimate output of demo. Could anyone please tell me what do I have to do avoid this error, and how do I get to .trr file?</div><div><br></div><div>Thanks,</div><div>Majid</div><div style="position: fixed; font-size: 10pt; "></div>
