I need to convert large reaction databases into flat ones (RDF to SDF), I need to get each individual structure from the RDF with its label and flag where it belongs (reactant, product). I was encouraged by the fact that when I point a MarvinView on RDF, I see exactly the result I would like to get - table with columns for structures and their IDs together with the ID that identifies the record. Indeed it is impossible to export this beautiful arrangement. I hoped that IJC might be suitable tool and tried to create an import template following the fields of my RDF file(s). However, I repeatedly failed to use this template for correct import of the file. I can describe the steps I made but do not know if it is worth bothering the whole audience ? I also tried to create a template considering the input is flat SDF but just text fields were respected, no structures. Questions: is IJC in general suitable tool for this purpose and how shall I specify the steps I made to eventually identify the mistakes ? Thanks.
