Dear Chimera Developers,
 
My group needs to calculate the inter-helical angle for a large trajectory.  We know Chimera can calculate the inter-helical angle for a conformation.  We are wondering what the easiest way to use Chimera to process the whole trajectory.  It is amber trajectory.
 
Thanks,
