trouble making second molmap

[Elaine Meng]

I get a traceback with molmap but it depends on context whether a given command gives a traceback or not. It seems to be related to having more than one map. For example, the first molmap works fine but the second gives a traceback.

open 1gcn
molmap :tyr 4
molmap :lys 4

... yet if I close the first molmap, reissuing the second molmap command above works. Here is the traceback:

Fixed.

Was caused by comparing two arrays of unequal length. This was in the code which determines whether the second molmap should replace the first molmap -- it is checking if they use identical sets of atoms.
