run_once or run_at method

7

We have a ``run_regularly`` method and ``network_operation``, but people often want to have something run just once and it's a bit of a fiddle at the moment. How about we...

Conditional string indexing of Synapses objects raises uninformative KeyError

1

Hi there! I just adapted the [test_synapses_to_synapses.py](https://github.com/brian-team/brian2/blob/b750fea045fc23bbf5e795ba6e7930dcc5be8747/brian2/tests/test_synapses.py#L2013-L2026) test to find out if I need to take care of some form of subgroups when the targat of a `SynapticPathway` is a...

The current Cython implementation for Cython (i.e. `rand()` and `randn()`) jumps through some hoops to call numpy's random functions via Python, buffering it in a numpy array. Since numpy 1.8,...

Subgroups and linked variables -- weak reference problem

3

As reported in the [discourse forum](https://brian.discourse.group/t/weakly-referenced-in-object-neurongroup-stateupdater/215), using a `VariableView` of a subgroup in `linked_var` will lead to a `ReferenceError`. The following example reproduces the issue: ```Python group1 = NeuronGroup(10, 'v...

Having an ``Equations.prefix`` and/or ``Equations.postfix`` notation that returned a copy of the equations with all variables prefixed/postfixed with a given string could make it much easier and simpler to write...

Structured equations with equation templates

38

Continuing the discussion from #1051 and the [Discourse forum](https://brian.discourse.group/t/standards-in-compartmental-modeling-libraries-of-mechanisms/148/7) here. No need to look at the actual code yet, it is just a quick&dirty dummy implementation to get things working....

Manual annotations/descriptions for objects

2

In the context of automatic model descriptions, it would be useful to be able to give additional descriptions/annotations to objects such as `NeuronGroup`. Currently, the only type of annotation you...

Macro definitions in equations

5

e.g. define `E(vT)=exp((E-v+vT)/tau)` and then use `E(15*mV)`, `E(40*mV)` in the rest of the equations.

Allow separate code and results directories for standalone mode

1

[This has already been mentioned in #251, but I'm pulling it out since it is quite simple to do and useful without full encapsulation support] Currently, you can give a...

Multiple standalone runs with change in parameters

1

Running multiple standalone simulations of the same model with different parameters is quite cumbersome at the moment. We can support this much more efficiently by using the trick I show...
