I discovered that using cxcalc for a rdf-file with -S option retuned a valid rxn file.
cxcalc -S charge 1.rdf -o 1.rxn
But not all properties are supported. Some of them like refractivity and logp return warnings that for reactions it is not possible to calculate them. Other ones like acc and don simply return errors.
Of course. these is a workaround: convert rdf to sdf first and then calculate what you need, but it is not always convenient.
Do you plan to add support of rdf files for these plugins in near future?
Thank you in advance.
