OEAtomStereoStyle¶
This namespace encodes symbolic constants used as bit-masks to indicate what and how atom stereo information is displayed.
The OEAtomStereoStyle
namespace contains the
following constants and nested namespaces:
Default
The combination of the following flags:
See example in Figure: Example of using the ‘Default’ atom stereo style.

Example of using the ‘Default’ atom stereo style¶
Hidden
Displays no atom stereo information. See example in Figure: Example of using the ‘Hidden’ atom stereo style.

OEAtomStereoStyle::Display¶
This nested namespace encodes symbolic constants used as bit-masks to indicate what atom stereo information is displayed.
Default
The combination of the following flags:
AtomStereo
Displays atom stereo information in the form of hash/wedge bonds. See example in Table: Example of using the ‘AtomStereo’ display style.
O[C@@H]1CN[C@@H](O)CC1 |
O[C@@H]1CC[C@@H](O)CC1 |
![]() |
![]() |
If the molecule is imported from an MOL or SDF file with an “either” stereo than it is depicted as a wavy bond. See example in Figure: Example of depiction of up, down and either (wavy) bonds.

CIPAtomStereo
Displays the CIP atom stereo information next to the corresponding atom. See example in Table: Example of using the ‘CIPAtomStereo’ display style.
O[C@@H]1CN[C@@H](O)CC1 |
O[C@@H]1CC[C@@H](O)CC1 |

The combination of the following flags:
OEAtomStereoStyle::HashWedgeStyle¶
This nested namespace encodes symbolic constants used to indicate the style of the hash/wedge bonds that depict atom stereo information.
Default
The default hash/wedge display style is
OEAtomStereoStyle.HashWedgeStyle.Fancy
Fancy
See example in Figure: Example of using the ‘Fancy’ hash/wedge style.
