PWRSpeaks.zip

This script identifies peaks in a power spectrum stored in a Spike2 result view.

The highest peak and up to 9 other peaks are marked with cursors and a table of up to 50 peak frequency and power values is written to the log view.

This script requires Spike2 version 4.00 or higher.

This is the first of two scripts for looking at the power of frequencies in user definable frequency bands.

The user is asked to specify an analysis region, this region is then split up into a number of epochs. Each epoch is analysed in turn and the power of frequencies within each band in each epoch for each channel are dumped to a data file.

This second script for doing spectral analysis in user definable frequency bands has a slightly different approach than SUDSA1. This script is more applicable to users who have lots of short epochs. There are several different analyses which can be performed and in each case the results may be dumped to a text file. The analysis modes available are:

• Dominant frequency
• Power of dominant frequency
• Total power of frequencies in bands
• Log power of dominant frequency
• Log total power of frequencies in bands
• Root mean square amplitude
• Cross correlation
