Hi Matt,

yes, I don't know why it is not there.

I tried with the pf.parameters function:

In [456]: pf.parameters['Initialdt']
---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)

/home/cthulhu/Repository/Python/yt scripts/5.primary_damping_analysis.py in <module>()
----> 1 
      2 
      3 
      4 
      5 

KeyError: 'Initialdt'

In [458]: pf.parameters['InitialTime']
Out[458]: 0.52818454582493

but since Initialdt is not there it is not able to find it. 

Can I ask if is there a way to tell Enzo to write out the Initialdt or should be there by default?

Thanks,
             Roberto

Weird that it's not there!  yt can get the cycle number if it's not.
You can see this and other parameters by looking at pf.parameters .
You can try using the "pprint" module to make it looks nice:

import pprint
pprint.pprint(pf.parameters)
