Christoph had previously inquired off-list about displaying arbitrary atom
properties in labels. Text of that message is below.
Christoph,
I have completed the work to allow the display of arbitrary user-defined
properties using the 'label' tags in Jmol. This should allow you to
display your nmrshift property ... or any other property associated with a
cdk.Atom object.
The syntax is:
label My custom property value is %{propertyName}
The curly brackets are required to delimit the property name.
Currently, only the CDKJmolModelAdapter implements this method.
Q: Are there file types that store arbitrary property values for atoms?
