Planar Angle Panel Features
- First Plane section
- Second Plane section
-
Define the planes by picking atoms in the Workspace or entering SMARTS patterns for the planes. These two sections have common features, described below.
- Atom N text boxes
-
Atom numbers of the atoms picked to define a plane. You can enter values directly in the text boxes, or edit the values.
- Pick option
-
Select this option to pick atoms in the Workspace to define a plane. The atom numbers of the picked atoms are displayed in the Atom N text boxes. When all three atoms have been picked, this option is automatically deselected. If you select it again, you can change all three atoms by picking, after confirmation.
- SMARTS text box
-
Enter a SMARTS pattern to define the atoms for the plane. The first three atoms in the first match of the SMARTS pattern are used to define the plane.
- Evaluate from Workspace button
-
Locate matches to the SMARTS pattern in the Workspace, and populate the Atom N text boxes with the first three atoms (lowest atom numbers) that match.
- Planar Angle text
-
Value of the planar angle. The value is displayed when both planes are defined.
- Compute for Selected Entries button
-
Compute the planar angle for the specified atoms for the entries that are selected in the Project Table. The angles are written to a CSV file.
