	Hi all,
Generating svg from struct.mol file gives me just the letter A. I use the following query
 
SELECT jc_molconvert((select structure from chem_structs where unit_id = -290265723), 'svg:H_off') FROM dual
 
and get sturct.svg
It doesn't seem to be the right behaviour.

	Hi Alena,
This is the normal behaviour, because the file contains a contracted s-group. Try to expand the molecule in the molfile.

	Janos, 
Thanks for your answer. I have sequential question - if there is any JChem search function or some other way to determine such kind of files with contracted s-groups?

	Ha Alean,
There is no function in jchem for this. You can use this API function:
public static boolean containsContractedSgroup(Molecule m) {
    for(Sgroup sg : m.getSgroupArray()) {
        if(sg.getXState() == Sgroup.XSTATE_C) {
        return true;
        }
    }
    return false;
}
