Hi all, I've managed to run with Sylvie's recipe and now the tagattribute problem seems gone.... I'm collecting all the 'corrupted' files and I'me going to run against them today.... There's a possibility that my holiday will be delayed until friday so, but I do not hope that, maybe tomorrow I'm going to be able to look if everything went well :) ! I'm going also to post as soon as possible the update chains for data and MC... Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
