<pre wrap="">Hey everyone,
I am trying to find the densest point in Gadget data in the
subvolume with left edge [700]*3 and right edge [800]*3 where 700 and
800 are in code units.
This is what I do [1], which was inspired by this page [2],
except I try and take the all_data confined to a region. The output
[3] says however where you will note the center is not inside the
region. It found the densest point in the whole data set, not the
region.
So how would I do this instead for a subvolume of Gadget data? Thanks.
