Hi,
 I would like to constraint a set of atoms coordinates to given
positions in my protein. I have only a pdb file (or gro file) containing
all the atoms in the wrong positions and a second file containing only
the CA positions in the desired positions. I have tested grompp with an
additional input pdb file as suggested in the manual but after
minimisation the result is not correct. Is it necessary that the two
files have the same number of atoms According to the gmx-user mailing
list it seems true. Is there an alternative way to do what I need ?
Thank you in advance for the answer.
Cathy
