Indexing with Denzo


Caution:  This tutorial is very outdated, nothing has been updated since 1995!

 

Disclaimer 2: If in doubt consult the HKL/DENZO Manual!!!


In case you just want to practice, you can use sample image data.

If you are on a Unix system, click here... Make sure you are in a directory where you have write privileges: 
$ set default $d:[B_user.subdir] 
If you want the graphics to appear on a node other than the current host you need to redirect with 
$ set disp /create /node=surf.u-of-hawaii.edu /trans=tcpip 
for a Unix target or 
$ set disp /create /node=px1 /trans=decnet 
for a VMS target system. Make sure you've disabled access control on the target node.

Start the display portion of HKL/Denzo at the VMS prompt in the background. If you are trying to display/index a 300 mm (2000x2000 pixel) image use the hkl2000 command, otherwise use hkl1200:

$ bg hkl2000 pbpm02_021.image hklpredictions

 


After a few moments you should see the image:

Note: the resolution information will in all likelihood be wrong because XDisplayF does not read the distance/wavelength information from the image header.

Now hit the  button and when Wladek is done  you will get something like  in your terminal window.


The image will now show black circles around all selected spots:

The x/y position of all selected spots is now in a file peaks.file, ready for auto-indexing with DENZO. Do NOT close the image window yet!
