Hi Chaava, You need to split the multi-state assembly into separate single-state objects. Then run APBS on a selection which includes all these objects. This is a huge system for APBS, you probably need to increase the grid spacing, otherwise it will take forever or might fail (PyMOL automatically retries several times with increased grid spacing if APBS runs out of memory).
Here is an example I successfully ran on my MacBook with PyMOL 2.1: # download assembly (multi-state object) set assembly, 1 fetch 3j7l, async=0 # split states into individual objects split_states 3j7l delete 3j7l In the GUI: - Open "Plugin > APBS Electrostatics" - Selection: polymer & 3j7l_* - Calculate Map with APBS > Options >> Grid Spacing: 2.0 (or larger) - Run Took about 20min to compute. Hope that helps.
