Wrong connectivity in Brunel10K sample #30

Closed denniskb closed 5 years ago

denniskb commented 5 years ago

In your Brunel10K sample code you're creating the connections P->E and P->I twice by calling connect_with_sparsity() one-too-many times in each case. This results in an observed synapse count of

#syn ~= 0.075 * #neurons^2

, when the expected count is

#syn ~= 0.05 * #neurons^2

Please confirm, thank you!

Hi Dennis,

Good catch, you are quite right the P->N connections are being created twice. This has slipped through from the iterating of the Brunel10K network for the SNNSimulatorComparison repository. I'll get it corrected.
