It would be nice to be able to create the NMR records (not only the sdf file). For this the mnova script should recreate the file tree of the original data of the manufacturer of instrument which generated the data. (with the spectra, the fid, the acquisition and processing parameters.
Currently, the export script generates a shell script to make such a file tree according to the path of the files of the spectra used in the document. But if/when files are not at their initial location, it is impossible to consitute the NMR record.
