Aside from the missing #ifdefs that Mark mentioned, this is also plainly wrong. The position restraints are part of the molecule definition, so now both sets of restraints are made part of the last moleculetype, which is the DNA chain. You'll have to have ; Include chain topologies #include "complex_Protein_chain_A.itp" #ifdef POSRES #include "posre_Protein_chain_A.itp" #endif #include "complex_DNA_chain_B.itp" #ifdef POSRES #include "posre_Protein_chain_B.itp" #endif I note that the position restraints for chain B are called protein too...
