AMBER: PMEMD limitation on NFFT

Dear AMBER users,

     I'm using a very long rectangular solvent box for my simulations
and I wish to employ PMEMD (AMBER8) for production run as it'll be
more efficient than Sander for such a case.

However, I came across this error:

| ERROR: nfft1 must be in the range of 6 to 256!

The box I'm using has dimensions:
  Box X = 410.713 Box Y = 93.892 Box Z = 55.886
Alpha = 90.000 Beta = 90.000 Gamma = 90.000
NFFT1 = 432 NFFT2 = 96 NFFT3 = 60

I wish to know if I can simply increase the max size in PMEMD code,
from 256 to 512?
(I know where to change it)

Can anyone please advice?
Thank you very much.


regards,
Choon-Peng
