Repeating units cannot be used with CHEM monomers, only with RNA or PEPTIDE monomers. The reason for that is that CHEM monomers have not a defined connection order (R1 goes to R2) for automatically creating polymers. This should be mentioned in the HELM specification and the Editor should show the parser error.
Thanks Markus - you are completely right.
I have updated the spec. The issue about the editor showing the parser error is wider than just this issue and will be taken up elsewhere.
Single monomers with brackets are valid and accepted by the webeditor.
PEPTIDE1{A'11'}$$$$V2.0
but I draw the following![image](https://user-images.githubusercontent.com/3986896/39309145-3415f60a-495f-11e8-9199-7d5657cddb58.png)
the correct HELM is generated
CHEM1{[Az]'11'}$$$$V2.0
and the HELM a molecule properties are calculated.However, if I clear the editor and paste in the HELM string
and the HELM string is changed to
CHEM1{[Az]'11'}$$$$V2.0
and click Apply, only one monomer is displayed:CHEM1{[Az]}$$$$V2.0
The webservices state that
CHEM1{[Az]'11'}$$$$V2.0
is invalid HELM.
