Hello! I have a gadget snapshot with a modified block structure (namely, it's dark matter only and I've calculated densities and smoothing lengths for the dark matter particles). I wrote a simple script to make a projection plot, which works just fine in serial, but when I run it in parallel (on two processors, just for testing), I get the following error:

Basically, the error seems to be that task 1 is not recognizing the field ('deposit', 'Halo_density') but root does.  This is my script:

I was just wondering how to fix this? Thanks!
