Simulation with user-defined emitter positions?

[dmitrits2018]

Greetings,
First of all, thank you for this work! I wonder if there is a way to setup simulation with user defined emitter positions to create test images.
From introduction notebook it is clear how to specify emitter position. But I can't find the way to use them directly.
the simulator, sim_test = decode.neuralfitter.train.live_engine.setup_random_simulation(param) creates random positions each time it is run.

Hey,
the simulator you set up in this way contains the forward model.
So for example you can do:
frame = sim_test.psf.forward(torch.tensor([[20,20,10]]), torch.tensor([1]))
To simulate a single PSF at position 20,20,10 with and an intensity of 1.
At the bottom of this function, you can see how afterwards the background is added and noise simulated: https://github.com/TuragaLab/DECODE/blob/master/decode/simulation/simulator.py

PS: If you have another question add @ASpeiser to the message so I get sent a notification.

Thanks so much. Works as charm! Dmitri
