Re: [Pcsim-users] How to make a field recordable?

[Mathieu D. <mat...@li...>]

Hello Dejan,

Under Python I would like to invoke getLinearInput like this:

inp_pop  = SimObjectPopulation(net, inp_model, 1);
nrn_pop  = SpatialSimObjectPopulation(net, , CuboidIntegerGrid3D(SIZE,
ORIGIN));
syn_proj = ConnectionsProjection(inp_pop, nrn_pop, syn_model,
RandomConnections(1.0));

N = 5;
for i in range(N):
  net.advance( i );
  print "Linear input: ", net.object(nrn_pop[0]).getLinearInput();


I get the following error:
ArgumentError: Python argument types in

     SquashingNeuron.getLinearInput(SquashingNeuron)

did not match C++ signature:

     getLinearInput(SquashingNeuron {lvalue})

Please find attached the code. Compilation is fine (though some warnings)
and the C++ unit test are passed (though the call to getLinearInput()
seems to return wrong values). I have tried to write a PyUnit test but I
don't know how to launch it.
There is a simple python test: launch test_SquashingNeuron.py (the error
message comes when executing this file).

Thank you so much.
Mathieu
