<div dir="ltr"><div>Hi Luigi,<br><br>It looks like there is a strange line in the parameter file of one of your datasets and yt is failing trying to parse it. You should be able to reproduce this problem by doing pf = load(<filename>) for each of the datasets. When you figure out which one it is, can you post it with yt_lodgeit.py and let us have a look?<br>

I'm trying to analyse (with the latest yt 2.5.5) a whole dataset from a<br>
cosmological simulation of mine, run with Enzo 2.1, and to extract the merger<br>
tree of the most massive halo in the box. I'm trying to run the script<br>

I am pretty sure that the paths to the files and to the database to be saved<br>
