Editing PPIIMoL (section)

== Usage (GUI) ==
Once loaded, PPIIMoL opens a Tkinter window with buttons to:  
* Load PDB (or use an already-loaded object)  
* Detect PPII (scan φ/ψ windows and list segments)  
* Scan Cα–H···O=C (optional geometric screening)  
* Style / Colors (apply the chosen palette)  
* Export (CSV reports; optional per-segment PDBs)  

Results are written to a date-stamped folder; selections/objects are created in the PyMOL session and colored according to the chosen scheme.
