SPICE netlist

[alex <alex@eel.upc.es>]

    I try to export SPICE netlist files and the LC SPICE can´t "run"
this line

    G_G1     NODE1 NODE2 LAPLACE {V(NODE3,NODE4)*58} {1/sqrt
(1+s/(2/3.141596))}

    It's a courrent source controled by voltage where its inpu/output
"frecuency" response can be expresed by it's LAPLACE funtion. I try
courrent sources controled by voltage ( I=k·V(NODE3,NODE4)) and it works
but it doesn't.
    ¿There's any type of Netlist file that uses this command line?
    ¿Can I use another version of SPICE for linux with LC that can do
it?
