Hi Joel, I added a Chimera volume file reader for DOCK bump map (*.bmp), contact map (*.cnt), and energy score (*.nrg) grid files. It allows you to open these files from the Chimera File/Open menu and use the Volume Viewer dialog to adjust colors and threshold levels interactively. This provides a better user interface for displaying DOCK grids. See the User's Guide/Tools/VolumeViewer documentation for details. Here is the new code: http://www.cgl.ucsf.edu/home/goddard/voldata.tar.gz It contains a directory VolumeData that replaces one already in Chimera version 1700. On Linux or Windows or SGI this would replace chimera/share/VolumeData, on Mac it replaces Chimera.app/Contents/Resources/share/VolumeData. You should probably rename the original VolumeData directory in case the new one causes you trouble. On Linux or Mac or SGI you can extract voldata.tar.gz using unix command "gunzip -c voldata.tar.gz | tar xf -". On Windows you can use an unzip program like WinZip. Tom
