I found in previous messages that it was neccesary to modified the mdread
file in sander adding these lines:





* else if (atype(1:1) == 'FE' .or. atype(1:1) == 'Fe') then
               x(l165-1+i) = 0.78d0 + 1.4d0 x(l170-1+i) =
0.00000d0 x(l175-1+i) = -0.00000d0
               x(l180-1+i) = -0.00000d0 x(l185-1+i) =
0.00000d0*
and reinstalling but I have already done this without success.

Any ideas of how overcome this problem?


Thanks, LucĂ­a
