Webeditor does not connect monomers in brackets

[ClairePA]

I enter the following HELM and click apply

PEPTIDE1{C'2'.A}$$$$V2.0

The HELM diagram is shown correctly

but the repeated cystine is not connected:

This means the mol wt and formula are wrong.

I was using http://54.83.135.171/HELM2MonomerService/hwe/examples/App.htm

[scilligence]

The problem is the web service don't return R1 in the molfile: http://54.83.135.171/WebService/service/Conversion/Molfile

Why are you converting SMILES to molfile and not picking up the molfile from the monomer definition?

[TianhongZhang]

For this particular example, can you just convert PEPTIDE1{C'2'.A}$$$$V2.0 to PEPTIDE1{C.C.A}$$$$V2.0 then show the structure?

[ClairePA]

I don't see why not internally, but we should see PEPTIDE1{C'2'.A}$$$$V2.0 displayed in the HELM box. Otherwise it doesn't look like we support the notation and we need to be able to generate the bracket notation from a drawing.
