This program for Scilab searches for primary peaks in the segments of brainwave signal spectrum which are much above the signal spectrum average.
Brainwave segments of 1 s are Fourier transformed, thresholded and merged if contiguous.
Selected segments are drawn in time domain, frequency domain and a narrow-band analysis at 75 Hz is attempted.

This program should detect strong external signals in brainwave recordings. Weak signals are not detected.
This program requires the "edf2ascii" utility, a set of EDF files with brainwave recordings in the "EDF/" directory and two empty destination directories named "founds/" and "losts/".
This is my first Matlab/Scilab program, apologies for the poor style but Scilab lacks and bugs prevent the writing of a pure code.
Use this software freely and fight the Remote Neural Monitoring system.
