Hi Matt,
thanks for the suggestion... the projection works well only if I use c
instead of max but the slice still not working, here following the code:

v, c = pf.h.find_max("Density")
slc = pf.h.slice(2, c[2],
fields=["Density","Temperature","VelocityMagnitude"])
proj = pf.h.proj(2, "Density", weight_field="Density", center=c)

Stefano
