Nuc isotope ratio error

[EricWalter]

I'm try to simulate hyscore with Ba and Sn, and it keeps giving me an error when I try to give it isotopes, so I went to the "spin system" section of the documentation and cut out the example:
Sys.Nucs = '63Cu,(32,33)S'; % 63Cu with enriched 33S
Sys.Abund = {1,[0.1,0.9]]; % 100% 63Cu, 10% 32S and 90% 33S

And even it gives the same error as my script:
Error using nucdata
Problem in isotopes list, entry 3 ('33)S'): Please specify one of 32S, 33S, 34S, 36S.

Error in validatespinsys

Error in saffron
What is the correct syntax? Maybe it has changed for version 6.

Helpful! Thanks for providing these tips.

saffron does currently not support isotope mixtures. If you have such a situation, call saffron separately for each isotopolgue combination. The function isotopologues should be useful for this.
