fit_neuron
fit_neuron is an easy to use python package for the fast estimation of generalized integrate and fire neural models from patch clamp electrophysiological recordings. The optimization routines implements a fitting procedure described in [RB2005] and [MS2011]. The package includes an easy to use interface similar to scikit-learn for fitting models to data and then making predictions with the fitted models. The routines used can estimate the models described in [RB2005], [MN2009], and [MS2011]. As described in depth in the documentation, the subthreshold parameters are estimated using linear regression and the threshold parameters are estimated using maximum likelihood. The fitting routine is built for speed: it estimates neuron parameters for 10 seconds of data in about 50 seconds on a quad core Asus laptop. fit_neuron also contains efficient implementations of the following spike distance measures: Victor-Purpura [DA2003], van Rossum [VR2001], Schreiber [SS2003], and Gamma [RJ2008] which can be used to evaluate the accuracy of estimated models, as well as provide measures of synchrony between spike trains.

Dependencies
Numpy
The standard python module for matrix and vector computations: https://pypi.python.org/pypi/numpy.
Scipy
The standard python module for statistical analysis: http://www.scipy.org/install.html.
Matplotlib
The standard python module for data visualization: http://matplotlib.org/users/installing.html.
Installation
The fit_neuron package can be installed as follows:
sudo pip install fit_neuron
The data for the fit_neuron package is then installed as follows:
sudo python -m fit_neuron.data.dl_neuron_data
Testing
There are two testing scripts that may be used. Both scripts are described in the documentation (http://pythonhosted.org/fit_neuron/).
The first script is far simpler and easier to understand but is less configurable:
python -m fit_neuron.tests.test_model
The more complicated and configurable testing script for fit_neuron can be run as follows:
python -m fit_neuron.tests.test
This will create a directory called test_output_figures in the current directory.
