I get the following when running grompp:

 

-bash-3.00$ grompp -f mdout_test.mdp -c SWNT_6_6_144.gro -p SWNT_6_6_144.top
-o

Program grompp, VERSION 3.3.1

Source code file: grompp.c, line: 448

 

Fatal error:

number of coordinates in coordinate file (SWNT_6_6_144.gro, 144)

             does not match topology (SWNT_6_6_144.top, 0)

-------------------------------------------------------

 

"You're Insignificant" (Tricky)

 

 

These of the commands I use to get to that point:

 

x2top -f SWNT_6_6_144.pdb -o SWNT_6_6_144.top -r SWNT_6_6_144.rtp

***Note: for some reason it does not generate SWNT_6_6_144.rtp

 

editconf -f SWNT_6_6_144.gro -o SWNT_6_6_144.gro  -d 0.5

 

genbox -cp SWNT_6_6_144.gro  -cs -o SWNT_6_6_144_b4em.gro -p
SWNT_6_6_144.top -maxsol 300

 

grompp -f mdout_test.mdp -c SWNT_6_6_144.gro -p SWNT_6_6_144.top -o

 

 

Also I notice that after running grompp it over writes the top file with:

 

# 1 "ffG43b1.n2t"

# 1 "<built-in>"

# 1 "<command line>"

# 1 "ffG43b1.n2t"

Any help or advice is greatly appreciated!
