Hi Votca users,

I am having trouble setting up my mapping for a system with 2 different 
molecule types. I am using a pdb file containing the all of the atoms of my 
polymer and then also the CG water beads that I will be using (which I have 
already clustered so there is just a 1:1 mapping for those).

My topol.xml file looks like this:

<topology base= "PEO16-PBO22-FULL.pdb">
  <molecules>
    <clear/>
    <define name="PEO16-PBO22" first="0" nbeads="401" nmols="128"/>
    <define name="WAT" first="51328" nbeads="1" nmols="6667"/>
  </molecules>
</topology>

I have run csg_dump --top topol.xml 

to check the mapping. The problem is that for my water beads, it seems like 
votca has reopened the pdb file as the index starts from 0 and the atom 
types are incorrect despite the fact that I say first="51328" for the water.

Is this the wrong way to declare multiple molecule types using a pdb 
topology?

I would be very grateful for any suggestions on this.

Cheers, Dan.
