Getting all the projections

[mervess]

Hello,

I was wondering if there is a way to return all the projections made over a simulator regardless of which simulator is used with PyNN.

For example, let's say these are the projections belonging to a simulation:
a = sim.Projection( ... )
b = sim.Projection( ... )
c = sim.Projection( ... )
... and I'd like to reach all three of a,b,c.

I checked the PyNN source code and the documentation, but didn't find any ways except Nest's GetConnections which is Nest-specific, and the Network class in PyNN, yet it could only come in handy if Network is used.

Best,
Merve

Hi Merve,

Currently , it is up to the user to keep track of Populations and Projections. The Network class was added recently to make this easier.

It would be possible to add a "magic" instance of Network (i.e. created automatically, Populations and Projects are added automatically, transparent to the user, accessible via the "sim" object). I don't have time to work on this, but I'd be happy to consider any proposals or pull requests for this feature.

Alright, I see 🤔 Thank you for the response Andrew.
