1 day ago Yes, right now it can only produce positive values. The way to do this would be to introduce spontaneous activity. I will assign myself to this. In the meantime, you can proceed with the other calculators. Good find!
After creating a spatial frequency tuning calculator instance called
spatial_freq_tuning_calc, I ran the following on the command line to get responses according to the Movshon 2005 fit function that includes a constant (in this case -1):r = vis.frequency.movshon2005_func(logspace(-2,log10(60),100),[ 10 5 12 1 -1]);Then I ran the generate_mock_docs method:[docs, doc_output, doc_expected_output] = spatial_freq_tuning_calc.generate_mock_docs('standard',1,'generate_expected_docs',1);Then I plotted the responses recorded in docs and compared them to r:figure;semilogx(logspace(-2,log10(60),100),docs{1, 1}{1, 6}.document_properties.stimulus_response_scalar.responses.response_real(1:100));hold on;semilogx(logspace(-2,log10(60),100),r,'--')The function ndi.mock.fun.stimulus_response seems to be constraining the responses it records in docs, such that they can never go below 0.
