I can't create a group containing peptide and oligo chains

[ClairePA]

If I try to create a group of the following:

I get this error message.

It should be possible to create a group from different simple polymer types. (That was the original purpose of groups)

[scilligence]

No you cannot. If yes, the monomer position in the group will be a problem. e.g. if you see position 1, it is hard to find which monomer this is. And the same when using a monomer symbol.

Why do you want to put two connected chains into a group? They are covalently linked already. Groups are meant to put separate chains together and you can define their ratios.

[ClairePA]

OK, but you can't group unconnected chains either.

[ClairePA]

You can create a group from unconnected or unconnected chains by creating individual groups for each chain and then grouping the groups.

This is the better way of solving the problem, therefore this issue should be closed.
