[Chimera-users] H bonds

[Randy Heiland]

I have a naive question - given the following pdb file:

ATOM      1  CA  ALA     0       1.125   1.534   0.000  0.00   
0.00      0    C

ATOM      6  H1  ALA     1       1.017   2.171   0.880  0.00

0.00      0    H
ATOM     12  H7  ALA     1      -0.420  -2.528   0.890  0.00   
0.00      0    H

when I display it in Chimera, there are 3 unbonded hydrogens - why is  
that and is there a menu item to create/display the bonds?

thanks, Randy
