| Input: X (matrix of neuronal activities) |
| Output: ICA_model (contains A, s, amongst other information) |
| 1: normalize data between (0,1)* |
| 2: subtract mean of each time series |
| 3: ICA_model = ICA(X) #data must be in column-format at this step |
we normalize using the global maximum and minimum of the trace set to preserve the relative difference between them
