Store in an Ntuple more than 15 columns of an ascii file

Hello all,

is there a way to read and store in an ntuple, more than 15 columns from an ascii file?
I’ve used basic.C from the tutorials which stores up to 15 columns of parameter values and works fine, but now my parameters have become more…

Any ideas?

Thanks in advance,

There is no limitation in TNtuple::ReadFile or TTree::ReadFile.
See documentation.
