I see what seems like a rectangular artifact when visualizing positions of particles emerging from a target in 3D using ntuple->Draw(“x:y:z”). This feature doesn’t exist in the geometry of the simulation (20 MeV electrons scattering in thin layers of Mylar, phosphor, and ferrite) and doesn’t show up in the 2D visualization of the data using using ntuple->Draw(“x:y”).
I have attached a 4-panel image to show this. (I have used the same mm scale for all axes). The top rows show 2D data (original and magnified), where the position data have circular symmetry as expected and there is no rectangular feature. The bottom row show same data in 3D from 2 different angles. There is a feature which is 80 mm in extent in the X direction which doesn’t appear in the 2D data.
I have changed the marker type and the color of the markers
As you see it looks like something is plotted in addition.
It is a bug a TTree:Draw. We will investigate.
Has the new patch bundle with this patch included been released? We updated to ROOT 5.34, and apparently this is not included, according to our IT support. Could you please confirm that this has been released?

I think he meant the fix is in the git repo.
You can either compile from the HEAD, or wait for the next release.

Thanks. Is there a way to find out when the next release will be?
This is what the IT staff here told me (grad students can’t download software directly):
“as far as I can tell they’ve not yet released the new patch bundle with your patch included. So I would have to try to pull it out of their repository and manually include it.”
You can follow the the release here: root.cern.ch/drupal/content/root … ease-notes
the last one was march 14
the patch I did was march 20
so it is in patches now … not in a stamped 5.34 version

Thanks for the info.
