[gmx-users] do_dssp file format

Yes, Mark i have taken a look in your previous message

To test my dssp program I took a pdb from the protein data bank: 1HRC. This pdb contains only one protein (and one frame). The DSSP program works fine with it and I obtain an output. So To test my do_dssp i also used this pdb. In this case when i choose MainChain 5 or other choices I obtain the same message described below and no output. I think, I have set correctly the DSSP environment variable because i have not the Fatal error:
DSSP executable (/usr/local/bin/dssp) does not exist (use setenv DSSP). Moreover i think that ten minutes is not to short to process one config indeed the DSSP program take less than 2 seconds to compute the secondary structure of the protein in 1HRC pdb file.

So i very frustrated...

This could easily be too short a time if there are multiple frames in 
your pdb file. I don't know whether you have or need to follow the 
suggestion I made last time... 
http://www.gromacs.org/pipermail/gmx-users/2008-January/031720.html

Also, per "man do_dssp" you need to have set your DSSP environment 
variable correctly.

Finally, test do_dssp on the same .pdb file you say works with dssp.

Hi all

When I run grompp with a trr input file using the command line showed below

grompp -np 2 -t run_1.trr -f md_2 -p topol_2.top -o run_2

it gives me a error:

Program grompp, VERSION 3.3.1
Source code file: futil.c, line: 340

File input/output error:
conf.gro

Could anyone tell me how I can fix it?

Thank you in advance.

you need to supply a conf as well. it will not be used.

Dear users,
                Thankyou for helping me regarding the topology file of my FNP inhibitor. I am facing one small problem understanding the topology file of my inhibitor. I have copied a part of my topology file.

what i dont get here is the significance of this pairing cos there are no bonds between these atoms.
