Hi Hernan,

In that case, I suggest you to define your own builder to build the
matrix you need.
I have given a try, but I cannot properly parse your data. The problem
is about separating column (is it 4 or 5 white spaces?). Having a ���,���
would help.

That should be a paste problem, matrix elements were delimited by tab.
