Greetings,

I am working on solute and solvent mesomolecules on which I use the Mesocite DPD module. 

The mesomolecules are coarse-grained structures, with the solute having 3 beads (A1,A2,A3) and the solvent too (B1,B2,B3).

After the simulation (when I obtain the final mesostructure \$structure), I want to assign the solute beads and solvent beads to specific sets in order to perform analysis on them (Mesocite RDF, gyration radius, and so on.). However I am struggling with the MaterialsScript command to use to do this. 

I tried using "FindPatterns by doing the following :

 my \$subPattern_solute = \$docsolute->Beads;
 my \$substructures_solute = \$structure->FindPatterns(\$docsolute, \$subPattern_solute, Settings(
 MatchProperty => 'BeadTypeName'));

\$structure->CreateSet(\$docsolute ->Name, \$substructures_solute);

which seems indeed to work and find the corresponding mesomolecules. However, the RDF calculation fails with error "no particles could be found".

What other command should I use to assign the sets to objects usable for analysis with Mesocite modules?

Kind regards,

Moncef
