Problems using THnSparse Projection

[Javier_Galan]

Ok, if I create the histogram using the technique indicated by @mczurylo at the following post I see no problem in the projection.

Unstable results when enabling MT and filling a THnD histogram using Take

Dear @eguiraud, in origin my problem was about filling a THnSparse object. There is another post about this here: So, in origin I was working with an THnSparse and while trying to make it work I thought it would be good to try with a THnD. I need to use a THnX so that I can in future use any number of variables. EDIT: I see now that perhaps the solution in previous post is that I need to use THnSparseD and not the abstract class THnSparse! I imagine the @mczurylo example will also work with…

So the problem seems to be related to retrieving the column data using Take. This post should be probably closed since the origin of the problem is more connected to the mentioned post.
