Welcome to the Insane Lipid Grid Generator! by Luis Borges-Araujo. 2024 @ ENS-Lyon.
This should help you define the initial lipid grid input used by insane & COBY to create lipid membranes.
- Define your lipid resname on the right.
- Bead by bead, following the order in your itp file, input your bead name and place it as you believe them to roughly be.
- Tap 'Save points' to get your output. This should be pasted in your insane.py script. COBY input formats are also available, albeit needing a bit of manual adjustment to bead charges."
Note: Remember that in CG resolution this process only needs to be roughly accurate. Typical location depths of the POPC headgroup, phosphodiester (PO4), lipid glycerol and acyl-chains are displayed. Beads can be moved by dragging. If you make a mistake you can delete a bead by right clicking.
