Other things without writing java

There are a few other things that you can still do without writing java.
First, your patterns, in param.xml, can have more than one rectangle.
This enables more complex data items.
You can also save the network. I've had reading the network implemented before, but it's not in the current version. It gets save as net.dat.
If you can look at the net, you can see how things are getting learned.
There are some execution things that can prove useful.
I've already mentioned run delay which can make the simulation go slower or faster.
Reset Run starts at cycle 0.
Set Stimuli Number selects how many are activated from the pattern.
You can also change each time to make it go through more patterns. This can be useful when learning large categorisation tasks.
Spontaneous activation randomly firees some neurons each cycle.
On the Set Parameters menu you can also set the likelihood a neuron is inhibitory, change the learning rate, and play with compensatory divisor which is a compensatory learning parameter.
Oh, you can also make multiple nets in param.xml, but they will not be connected.
