events.write_simput_file cannot save the file in any special path.

[tekkamanmaverick]

Hi John, If I use events.write_simput_file(path+name, overwrite=True) to write the fits file, the next operation soxs.instrument_simulator will not find the phlist.fits. The path which is path/path is not match. So write_simput_file can only save the file in the current path.

Can you put a short script here that reproduces this and the exact error message you get?

I thought about this today a bit, and I decided I need to research how the SIMPUT library handles this because I'm not sure if their files support absolute paths or not (I suspect they do).

This was resolved in pyXSIM 3.0, so closing.
