cdutil climos fail on file variables.

[doutriaux1]

>>> o3tor_anom = cdutil.ANNUALCYCLE.departures(o3tor) this is where I get the error. 


Here is the complete error stack:

The complete info for the "o3tor" variable is given below, just in case you think there is something wrong with the variable:

@durack1 I can't reproduce, the following works for me. Please re-open if you can still reproduce.

import cdms2
import cdat_info
import os
import cdutil

pth = cdat_info.get_sampledata_path()

print pth

f=cdms2.open(os.path.join(pth,"tas_dnm-95a.xml"))

s=f["tas"]

dep = cdutil.times.ANNUALCYCLE.departures(s)
