[Mesa-users] MesaReader Python Plotting Issue

[Desmond Helmut Grossmann]

Dear Madison,

I just tried it to plot with mesareader module myself (with the new version
of MESA) and I encountered the same problem. The solution, that worked for
me was:

In the History file (in LOGS directory), which is accessed by mesa reader,
in the 4th column (the one with the stellar age) it provides the version
number of MESA SDK (basically just for information it doesn't matter for
plotting). However, in my case it shows the following:

"x86_64-osx-10.10-10.14-2019

At the end of the version number there is a quotation mark missing. If you
add this quotation mark by hand, save the file and rerun the python script
it should work out fine.

Greeting s from the MESA Summer School

Desmond
