In the latest 10th December 2001 versions of WinGX and Ortep-3, it is possible to have
Ortep-3 automatically update the RES file so you can instantly see
the state of the ORTEPs from the most recently cycle of refinements.
First, under File, System, Preferences, set the Ortep-3 properties to Read RES file on starting.
Now while refining a structure with Shelxl97 within WinGX, load up the
RES file into Ortep-3. (this can be quickly done by click on the Ortep-3
Icon in the Icon bar of WinGX)
In the following screen dump, the structure has been refined Isotropically.
Ortep-3 can also be sized as a window and it will rescale accordingly.
For this example, using your preferred method, either directly editing the
Shelx RES file or using the SXGRAPH GUI Shelx editor, set the atoms isotropically.
At the completion of the refinement cycles, Ortep-3 will automatically load the
new RES file so you can quickly examine the state of the newly refined ORTEPs visually.
