Description

NAPa 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 with spike time randomization, spike time dithering/displacement or train shifting/dithering. It improves over the NAss program by allowing for additional statistics, especially statistics that do not rely on time binning, but work directly on continuous time measurements.

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

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 (where the first refers specifically to NAPa, while the next two refer more to NAss, although NAPa covers most of the content as well):
