 From the example I showed in the previous thread regarding the DSSR
change I would suspect that the first base would be residue "A" number
"10" from chain "D". And I would suspect the "1" being the model number.
But because it wasn't included in the former residue selection
expression I am not really sure.

The syntax for the selection expression is the same as before:
   select [A]10:D
   select [T]29:E

Or if you would add the (suspected) model number it would look like this:
   select [A]10:D/1
   select [T]29:E/1

You can split the 'nt1' and 'nt2' strings by "|" into an array and then
build the selection expression as a string:

----- Jmol commands ----------
nt1 = auxiliaryinfo.models[1].dssr.pairs[9].nt1.split("|");
nt2 = auxiliaryinfo.models[1].dssr.pairs[9].nt2.split("|");

res_nt1 = "[" + nt1[4] + "]" + nt1[5] + ":" + nt1[3] + "/" + nt1[2];
res_nt2 = "[" + nt2[4] + "]" + nt2[5] + ":" + nt2[3] + "/" + nt2[2];

select @res_nt1;
select @res_nt2;
------------------------------

I currently cannot post to the 'jmol-users' list because my recent email
address change wasn't confirmed there yet. Please forward my answer to
the list so that others can also see it.

Regards,
Rolf
