[gmx-users] changing dihedral angles in a pdb file

[Y U Sasidhar]

Is there a utility which will read a pdb file, change certain selected 
phi,si,chi1, chi2 etc to specific values and write the changed pdb file 
? spdbv ( deep view ) has a tortion tool but it doesn't display the 
angle being varied. It becomes difficult, though not impossible to set 
specific torsion values.
