[yt-users] 'FLASHDataset' object has no attribute 'field_info'

[Daniel Fenn]

Hi,

I'm trying to calculate the center of mass of my FLASH dataset using the
following:

import yt
ds = yt.load("path/to/file")
ad = ds.all_data()
print ad.quantities.center_of_mass()

However, the last line throws the error: 'FLASHDataset' object has no
attribute 'field_info' .

As a test, I ran

ds.field_info["flash", "temp"]

which gives the same error.

Can anyone give me any advice on what's going on and how to get past this
error?

Thanks,

Dan
