Dear justin Thank you for your previous reply,
Finally I Have Found out problem When I Shrink My system Using Script The Size
of the box at the end of System_inflated.gro file is not as i Have Assigned
previously it has been Changed From Box size from 6 6 6 to 27 27 6.00
when I edit The end line of Output file Everything become Ok (when i Solvate
it has been solvated with 1024 sol Molecules)
You should not manually change the box vectors. The whole point of InflateGRO
is to expand and compress the system. Leave the box vectors it assigns alone.
Now Can i use different DPPC Cut-off Value (20 or 25 ) ? or Different
Scaling Factors (instead 0.95)
Larger cutoffs lead to greater numbers of lipids being deleted and thus extends
the time it takes to compress the system back. The value of 14 suggested by the
authors of the script has always worked for me.
Because When i Use 14 for my System No Lipid Molecules has been Deleted
That's certainly unusual.
Also There is sudden Shrink in APL When I go from first iteration and EM to
Second Shrink ( from 93A to 4.7A)
Why Such Drastic Fall of APL Occurs?
Without seeing your commands and the actual screen output, I can't comment, but
I find this highly unlikely.
How to Rectify this Problem?
No clue. Very little of what you are saying makes any sense to me.
