WinGX and viewing Nonius CCD Frame data
WinGX allows you to easily view your raw frames and do basic visual analysis. e.g., why some 1 1 1 reflections are big outliers. In the following example, you will be taken through some of the functionality of the WinGX
A complete set of raw data uncompressed frame images used in this example is in a 156 Meg Zipped Nonius CCD Example Raw Frame and import.cif Data
To start the KCD ImageTool, via the WinGX menu, select,
Data, KappaCCD, KCD ImageTool. If your uncompressed
frame images are present, it will display the first frame.
As examples of some of the functionality, select Utilities, Primary Beam to
view where the primary beam is stated as being located with a red cross.
Select Utilities, Primary Beam to
see which spots were intergrated. Clicking on an integration will tell
you which HKL it belongs to.
You can find out which frames have specified HKLs by using
Utilities, Find Denzo HKL (in this case the 1 1 1 HKL).
This could take some time to provide the following output.
After running Utilities, Find Denzo HKL a frame will be
displayed with a found HKL. And you can then scroll through the
frames having the requested HKL (in this case, the 1 1 1 HKL). You
can see in the following screen image the 1 1 1 is obscured by the beam
stop; showing why it could be an outlier reflection.
