The topotools tutorial here:
  https://sites.google.com/site/akohlmey/software/topotools/topotools-tutorial---introduction

..suggests the common parameterization:
  topo somecommand someargument someotherargument [...] [-sel ] [-mol |top]

I think if you add -mol xxx, you should be in business.
I think that by default it operates on the top molecule.

Best,
