[yt-users] pc.save with old Enzo

[Elizabeth Tasker]

Hi,

I'm trying to analyse an older Enzo simulation which writes its output in hdf5 but with files that look like:

GT_RotFrame_128AMR8_stars_0200.grid.cpu0029

the script runs fine until it reaches pc.save(fn), then I get:

AttributeError                            Traceback (most recent call last)

Is there an easy fix for this? If it helps, an example data set is at:

http://www.physics.mcmaster.ca/~taskere/GT_RotFrame_128AMR8_stars_0200.tar.gz

(about 650 Mb) and the yt script:
