[mesa-users] mismatch between structure files and rows of history file

[Bill Wolf]

Hi Dave,

Additionally, photos, and I believe profiles, are saved at "key" events, like the onset of core helium burning, for instance. This is probably where the bonus profiles are coming from.

As for Josiah's point, you may find on the "tools" section (specifically the python part) of mesastar.org a log scrubber script that will remove excess lines from your history file so that the backups, retries, etc. won't be gumming up your data. It always chooses the most recently written entry for a given model number, so your history file will always be properly ordered with the most recent data. Good luck!

Regards,

Bill

Specifically, in this run, rows 1995 and 1996 both have model_number 19910, but different values for physical quantities.  Row 1996 has the physical quantities that correspond to the profile file that has this model number (profile1994.data).

So when you make a plot in which you don't want to include discarded steps, you need to remove them yourself.   I do this by using model numbers --i.e., for each line, I discard any previous lines in the log that have a model number >= this one.
