+Ray-trace a PyMol session on cheaha
+
+WARNING: PyMol licensing issues have not been addressed.
+
+Sample session to render can be found in test_1aon_struct_spectrum.pse
+which comes from the "[Huge Surfaces](https://pymolwiki.org/index.php/Huge_surfaces)" PyMolWiki page
+
+This project provides 2 different ways to run a pymol ray job:
+
+1. bash shell script that can be submitted with sbatch
+2. Snakemake pipeline script (coming soon)
+
+## sbatch usage
+
+By default, it loads the session "test_1aon_struct_spectrum.pse" and creates the image "test_1aon_struct_spectrum.ray.1200x900.300dpi.png", which takes about 90 minutes to run.

+cd pymol_ray_pipeline
+sbatch job.80s_ray_1200x900_dpi300.sh
+```
+this should launch a cluster job, which will wait in the queue.
+You should get 2 emails:
