Description

NAss is 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 randomization, or activity corrected spike time randomization. The program expects the input file to be in a simple two column format, with the first column holding the neuron id (> 1) 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.

NAss has been superseded by the NAPa program.

If you have trouble executing the program on Microsoft Windows, check whether you have the Microsoft Visual C++ Redistributable Packages for Visual Studio 2015 installed, as the library was compiled with Microsoft Visual Studio 2015.

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