Dear FLASH Users,

I hope you're doing well. I'm currently working with FLASH and trying to
read opacity data, but I need some guidance on how to properly handle it.
Specifically, I’d like to know:

   1. What is the best way to convert opacity data from TOPS or SESAME
   formats into IONMIX (IMX) format for use with FLASH?
   2. How does FLASH read opacity data (plank emission, plank
   absorption and rosseland) from imx files? I will try to write a script to
   convert the files i have to this format otherwise

I attempted to use opacplot2 for the conversion, but I ran into errors, and
it didn’t work as expected. If anyone has experience with this or
alternative suggestions, I’d really appreciate your insights.

Thanks in advance for your help!


Regards,
Youssef
