[yt-users] Star particles error

[Fernando Becerra]

Hi,

I'm using the following script to analyze my data:

from yt.config import ytcfg; ytcfg["yt","serialize"] = "False"
from yt.mods import *
from yt.analysis_modules.star_analysis.api import *
pf = load("DD0088/g1e10s1e11dm1e12_0088") 
my_disk=pf.h.disk([0.5, 0.5, 0.5], [0, 0, 1], 50/pf["kpc"], 10/pf["kpc"])
sfr = StarFormationRate(pf, data_source=my_disk) 

and I'm getting this error: http://paste.yt-project.org/show/2004/ but yt is actually reading star particles, if I try to get the number of particles or their masses there's no problem (http://paste.yt-project.org/show/2005/), so I suppose the problem is only when reading "creation_time"... or maybe the file is corrupted? I'm using yt-2.2, but with yt-2.3 a similar error occurs.

If it's necessary I can upload the data, but its ~250MB.

Regards,
Fernando.
