Dear:
I am going to calculate the area/lipids for my membane system and I found
that GridMAT for area/lipids calculation is not that reliable since I
calculate by XY/(0.5 lipids number) for the pure well equilbirated POPC lipids
system, my values is 67 which is close to experimental data but GridMAT give
me something 72.....
I am just wondering is there any alternative methods?
Since that calculation is one of the main purposes of GridMAT, I'd suspect
you're comparing two different quantities, or not calculating one correctly.
We did several calculations on pure lipid bilayers in our initial testing of
GridMAT-MD and always found it to agree very well with other methods, so this
outcome is very surprising to me. In the absence of more information that would
be necessary for troubleshooting, I do not see a reason for the discrepancy.
