Import Probe Dialog Box

This dialog box allows you to pick the probe atom on a probe molecule and set an orientation of the probe atom with respect to the target.

To open this dialog box, click Import from Workspace in the Probe Grid Scan Panel.

Using the Import Probe Dialog Box

First, pick the atom on the structure in the Workspace that you want to use as the probe atom. This is the atom that is placed on a grid point when the search is done, and whose van der Waals radius can be used to define the grid.

When you pick the atom, a yellow arrow is placed on this atom. It is initially aligned on the y axis (the vertical axis in the Workspace). To change its orientation, you can rotate it about any of the three axes, using the dials in the panel. The orientation is used in the initial placement of the probe: it defines the vector from the probe atom (placed at a grid point) to the nearest target atom.

Import Probe Dialog Box Features

Pick option

Select this option to pick the atom in the Workspace that serves as the probe atom, which is the atom that is centered on a grid point.

Orientation controls

Change the orientation of the probe atom to the nearest atom on the target. The controls rotate the vector (given in yellow) around the specified axes (x is horizontal, y is vertical, z is out-of-plane).
