-- preliminary only (assumes _atom_site.label_seq_id same as _atom_site.auth_seq_id
and mmCIF only -- thus PDBe, not RCSB for now, at least)
-- fetches http://rna.bgsu.edu/rna3dhub/loops/download/xxxx
-- hairpinLoops, internalLoops, junctions
-- allows for such constructs as:
select within(rna3d,"hairpinLoops")
select within(rna3d,"hairpinLoops where index=5")
x = getproperty("auxiliaryInfo.models[1].rna3d.internalLoops.5")
print x
{
