I am having troubling using the correct flags for my input files for equilibration and production for my absolute binding free energy calculations. I know I need to use timask1 = timask2 = ':LIG', scmask1/2 = '', ifsc = 1 for charge decoupling, and then timask1 = scmask1 = ':LIG', timask2 = scmask2 = '' and ifsc = 1 for vdw decoupling. Is that correct? Are there any other important flags I am forgetting? Please help!
