We have developed a Chimera tool to color by bfactor or other attributes but it is not yet released. We expect to have a new release in the middle of May.
Hi Padma, I'd like to supplement Tom's answer to say that an undocumented version of the coloring tool he refers to did make it into the 1917 snapshot release, which you could download, or you can use the alternatives Tom described instead. If you do go with the 1917 release, you bring up the coloring tool by selecting your model in the Model Panel and clicking the "render attrs..." button. In the dialog that comes up in response you would pick "Attibutes of: atoms", and then "attribute: bfactor". This will show you a histogram of the bfactor values and 3 color markers used to indicate the color range to use. You can ctrl-click on the histogram to add/delete markers. Normal clicking on a marker will allow you to adjust its color using the color well beneath the histogram. You can also drag the markers left/right with the mouse or type in a value for you last selected marker in the "Value" entry field. This interface will be changed and improved in the next release, but is basically functional for what you want to do now.
