hi,
i just discovered the reason root was choking on long ntuples: it is
actually due to a cint command-length limitation, not something inherent
in root. here is an example of how to put all you would ever want into
one ntuple:
--chris
{
TString tt;
tt+="ttl0t:ttl1t:ttl2t:ttl3t:ttl4t:ttl5t:ttl6t:ttl7t:";
tt+="ttl8t:ttl9t:ttl10t:ttl11t:ttl12t:ttl13t:ttl14t:ttl15t:";
tt+="ttl0b:ttl1b:ttl2b:ttl3b:ttl4b:ttl5b:ttl6b:ttl7b:";
tt+="ttl8b:ttl9b:ttl10b:ttl11b:ttl12b:ttl13b:ttl14b:ttl15b:";
