Sorry about that. I didn't see that in the inbox. Excuse me...
What am I thinking about are some notes in the tutorial. For example
The above command centers the protein in the box (-c), and places it at least 1.0
nm from the box >edge (-d 1.0). The box type is defined as a cube (-bt cubic)
So, can I make a bigger problem by setting that to 4.0 nm? What about other box
A cubic box is the least efficient, so to achieve your goal of a slower
simulation, stick with a cube. Increasing the buffer size around the
protein will lead to more waters being added.
[ molecules ]
; Compound #mols
I see 8 green points in the figure in that page. Can I increase that to put
more molecules in the cube?
What are the blue dots in the figure? Are they atoms? If I want to increase the
number of atoms, should I use another pdb file and run pdb2gmx again?
The 8 Cl- ions balance the charge on the protein. Don't try to change this.
The blue atoms you see are water.
; Name nrexcl
Can I blindly increase that 3?
No, because then you're going to start breaking the model physics,
whether or not you care I don't know.
Can I use another pdb file (other than 1AKI) and follow the same procedure?
Generally, yes, but don't follow it exactly because the number of ions
added depends on the charge on the protein.
Generally, the type of my questions are like those.
