Extending the 'preConds' and 'postConds' parameters in netParams.connParams to accept string-based functions
Is your feature request related to a problem? Please describe.
I'm improving the topological connectivity in the thalamus model and I would like to be able to specify the 'convergence'/'divergence' as a parameter for connectivity.
Before, to implement the topological connectivity, I added the 2D/3D positions as string-based functions in the 'probability' field. That allows me to define connections between the positions of the cells, but I lose control over how many post synaptic cells I connect to, and had to adjust that manually.
Describe the solution you'd like
Now, if we extend the 'preConds' and 'postConds' fields to accept string-based functions, I should then be able to use the x,y,z distances and still define 'convergence'/'divergence' between the cell populations.
Describe alternatives you've considered
I tried creating many populations to connect based on the population position, but still, I need the connectivity to be based on the distance between the cells from the pre and post populations (e.g. if dist_x<200 and dist_z<100)
Additional context
This fix was suggested by Salva, but any other alternative that allows me to have a rule to connect two cells based on their positions should already solve my problem.
Example of the previous topological connectivity I had, but in this case I could not fix the value of how many cells the 'pre' would connect to in 'post'.
