Cannot create grid.csv file about spexxy HOT 4 CLOSED

Did you specify a regular expression for the extraction of the parameters via --from-filename?
You can also create the file manually. It just needs to be a CSV file with Filename column and one column per parameter in the grid, like in the example:

Filename,Teff,logg,FeH,Alpha
PHOENIX-ACES-AGSS-COND-2011/Z+0.5.Alpha=+0.50/lte02300-0.00+0.5.Alpha=+0.50.PHOENIX-ACES-AGSS-COND-2011-HiRes.fits,2300.0,0.0,0.5,0.5
PHOENIX-ACES-AGSS-COND-2011/Z+0.5.Alpha=+0.50/lte02300-0.50+0.5.Alpha=+0.50.PHOENIX-ACES-AGSS-COND-2011-HiRes.fits,2300.0,0.5,0.5,0.5

Ok, it seems I misunderstood the functionality. Doing what you suggested and creating a CSV file manually got me past that initial problem. I think I understand how it works now, I’ve been testing different approaches for different files- Are there any specific guidelines on the format of the FITS files? e.g. what metadata should there be in headers, etc.? Apologies, I know this isn't particularly relevant to the original issue.

Thanks for your help.

No, sorry, no guidelines at the moment. But if there are CRVAL1/CDELT1 keywords in the header, it should be fine. You can simply try to plot a spectrum via "spexxytools plot" to see whether spexxy can read it.

Ah ok, that's good to know. I noticed that not having CRVAL1 was a problem.

Cheers, will close now.
