NAss - Finding Neurons Participating in Assemblies

Download

Description

A program to analyze parallel neuronal spike trains for assembly activity with the help of different statistics. A p-value is obtained by creating surrogate data, either by trial shuffling, spike time shuffling, or activity corrected spike time shuffling. The program expects the input file to be in a simple two column format, with the first column holding the neuron id or a trial start or end marker (0: start, -1: end) and the second column stating the spike time.

Call the program with no arguments to see a list of options.

Details about the application, the statistics, and the methods used for generating surrogate data can be found in these papers:
