remark  file topallhdg.pro
remark   geometric energy function topology for distance geometry and
remark   simulated annealing.
remark 
remark   history:
remark
remark     XPLOR topology file TOPALLHSA.PRO, all hydrogens, 
remark     for simulated annealing, to be used with PARALLHSA.PRO
remark     based on TOPALLH6.PRO.
remark     internal coordinates from TOPH19.PRO.
remark     fixed bug in CISP patch, VLH (7/23/92)
remark     added patch for proline cis bond CIPP, VLH (7/23/92)

! all dihedrals defining planarity have been converted to impropers,
! the only dihedrals left are around rotatable bonds.
! some additional impropers were included in the rings to define planarity
! better. patches are included to define chirality at stereospecifically 
! assigned prochiral centres and convert from trans to cis peptide bond.
! modifications by M. Nilges and P. Kraulis.
! added stereospecific impropers for all pro-chiral centers (ATB)
