Dear yt-users, I am using this script <http://paste.yt-project.org/show/135/> to run Rockstar and it has worked great for me for years. Here is the situation now: I ran rockstar a few weeks ago and since then have several additional enzo data dump outputs I would like to add to my merger trees (done with consistent-trees). To meet data quota requirements, I needed to move several of my outputs to storage (already got the rockstar outputs on these), which I believe is causing my rockstar restart to fail (see error here <https://pastebin.com/ABMx3wzZ>). In the script mentioned above, I tried removing find_outputs=True on line 51 and adding the keyword initial_redshift=11.749 to get_time_series() on line 59. I keep getting the same error. I have also updated datasets.txt as well as rockstar.cfg and restart.cfg to the desired RESTART_SNAP and NUM_SNAPS. What am I missing? Is there a way to run a restart on Rockstar with some of the previous files (already processed by rockstar) missing? Thanks in advance.
