Dear Users,

 I am unable to generate the file.gro with  gromacs.4.6.3-1.
However, I have obtained the file.top after using

pdb2gmx -f TTb.pdb -o TT.gro -p TT.top -ignh
...

This appears after I have change the version of gromacs from 4.5-4 to
4.6.3-1
I am not able to find any error in the output.

I will be very grateful the receive any suggestion...

I wish you all a blessing weekend


Collins
