Hello Angeliki,
IN NEST 3.5, one can provide relatively complex expressions for connection rules, including weights, see
https://nest-simulator.readthedocs.io/en/stable/neurons/parametrization.html
This mostly applies to networks with spatial structure, though.
If you would be willing to share more details about your network and simulation scripts, I could provide more detailed suggestions. You can send that information directly
to my mail address if you do not want to make it public on the mailing list.
Best,
Hans Ekkehard

Thank you for the reply.
I will attempt to migrate to 3.5 and see if it works faster.
i know for a fact that i can benefit from the collocated synapse class to draw both ampa and nmda connections between the same neurons.
but can you elaborate a bit on the last thing you mentioned:
"Depending on what kind of "manual" manipulation of synaptic
weights you need to do, it might even be possible to include this in connection creation,
so you can avoid GetConnections() altogether."
the scenario: i initially draw non specific recurrent connections within the global neuron population using a connection probability. The network is organized in hypercolumns that contain minicolumns. Knowing the minicolumn index of the pre and post populations
i want to upregulate the weight. Can that be done without a call to getconnections?
Thank you for your time
Angeliki
