O

  • Description

    a model building application for X-ray crystallography.

  • Usage Notes

    As of version 12.0, O no longer requires a license file.

    To use custom O data files (rotamer database, interface files, etc), you must override the ODAT environmental variable to point to your own directory.

    • Open a tcsh new shell and source /programs/labcshrc
    • echo $ODAT (note the current O data directory
    • cp -Rp $ODAT ~/o_data (copy the current O data files to your home directory)
    • setenv ODAT ~/o_data (you can add this to your ~/.cshrc after the 'source /programs/labcshrc" line)

    Copy your custom files to ~/o_data and then run your newly customized O.

    O works with SGI Dials. If you're using OS X, you should download and install the most recent USB<->Serial adapter driver for dials use from David Gohara's website. The download file contains a PDF with instructions on installation and set up.

    An unexpected side-effect of Alywn Jones's decision to write Frodo, one of the first computer graphics programs written for Xray crystallography, was learning to swear in German. His teacher? Johann Deisenhoffer, the 1988 winner of the Nobel Prize in Chemistry.

    “He was always using my experimental versions,” said Jones, then at the Max Planck Institute for Biochemistry, now professor of structural biology at Uppsala University in Sweden. “He used to swear at me when my program exploded, which it often did.” Back then, in 1976, Jones had happened into computer graphics. “I took a wrong turn and I just kept going,” he says, his voice just slightly less gritty than that of The Boss.

    Jones programmed on what at the time was a sophisticated computer. “I could ...
