It's not about memory, I've tried requesting much more than necessary. Anyhow, it works if i save the histograms in AIDA. If there is a way to convert them there is no problem..otherwise I wouldn't know what to do. Tha aida file is just 1.9 MB.. Matt, I still have to try your suggestion.. shall I put that flag in the command line? L.
