Hi, I was just trying to compute the halos from a Nyx data. While running the halo finder it stops saying ........ yt.data_objects.field_info_container.NeedsDataField: (['particle_mass'])
Below is the code, results and the list of fields available. In the list I have "particle_mass_density" instead of "particle_mass". Please suggest me how I can make it running.
Thanks, surajit
