[yt-users] Bad object header error

[Jean-Claude Passy]

  Hi all,

I have slightly modified some output data from Enzo. I edited the 
datasets in the .cpu**** files, the .boundary files, the restart file, 
etc... So far, I was using only a unigrid and I was able to restart Enzo 
with this 'edited' data and to manipulate it without any problem.
Now, I am tried to do the same thing on a data with several grids and 
the following error occurred:

I have included the script. I can upload the data in a drop.io is necessary.

Does anyone have an idea how to solve this problem ?

Thanks for your help,

JC
