Dear all,

I'm having a tough time using the super command correctly.  I want to superimpose two 5S structures.

In pymol, I'll do the following

load 2awb.pdb
load 3cc2.pdb

create ec-5s, 2awb and chain a
create hm-5s, 3cc2 and chain 9

If I issue super ec-5s, hm-5s then the cryptic error "ExecutiveAlign: invalid selections for alignment. would appear."

Issuing super /ec-5s//a, /hm-5s//9 does not help either.

What am I missing?  align /ec-5s//a, /hm-5s//9 works just fine though...

Any help from the community would be very appreciated.
