370:CH4N2:C_21 is wrong, it needs to be 1:CH4N2:C_21 (same for the
other string starting with 370: in ch4n2_mapping.xml, file attached)
The first number in the string is the local residue number inside the
molecule and CH4N2 only has one residue.

You can run "csg_dump --top urea-water_1atm300K_NPT.tpr" to see what
names votca reads for the topology file.
