Compare Two Tool

Notice: Due to planned facilities maintenance, the RAD webtools will not be available from May 22-25th. Sorry for any inconvenience.

With this tool, you provide two sets of RAD angles, corresponding to two different structures. The tool will then calculate the Euler-Rodrigues angle between the structures, as well as the difference in tilt. The provided angles may be obtained using RADtool, or they may be drawn from values in the Ribosome Analysis Database. Animations between any two structures can be generated with RADtool.

Structure 2
Provide a second set of RAD angles that define
a specific orientation of the head, or body.
