Hi,

I am trying to use the comand cmd.super() to calculate the rmsd between the sidechains of two proteins using

cmd.super('%s and not name ca+c+o+n' % obj0, '%s and not name ca+c+o+n' % obj1)

And I get this error
ExecutiveAlign: invalid selections for alignment.

It seems to me that the problem is related to the exclusion of the "ca" atoms. because:

cmd.super('%s and not name c+o+n' % obj0, '%s and not name c+o+n' % obj1)

works, but

cmd.super('%s and not name ca' % obj0, '%s and not name ca' % obj1)

does not work.
