This consists of setting 1-2, 1-3 and 1-4 distance based on bond lengths,
|
|
bond angles and torsion angle ranges. Optionally 1-5 bounds can also be set,
|
|
in particular, for path that contain rigid 1-4 paths.
|
|
|
|
The final step involves setting lower bound to the sum of the vdW radii for
|
|
the remaining atom pairs.
|
|
|
|
\param mol The molecule of interest
|
|
\param mmat Bounds matrix to the bounds are written
|
|
\param set15bounds If true try to set 1-5 bounds also based on topology
|
|
\param scaleVDW If true scale the sum of the vdW radii while setting lower
|
|
bounds
|
|
so that a smaller value (0.7*(vdw1 + vdw2) ) is used for
|
|
paths
|
|
that are less five bonds apart.
|
|
|
|
<b>Note</b>
|
|
For some strained systems the bounds matrix resulting from setting 1-5 bounds
|
|
may
|
|
fail triangle smoothing. In these cases it is recommended to back out and
|
|
recompute the bounds matrix with no 1-5 bounds and with vdW scaling.
