1. BCseis.m is the MatLab Graphical User Interface for interactively investigating a time series file in SAC format.

2. BCseis_process.m is an inline MatLab function for processing many seismograms. A sample driver MatLab program, BCseis_process_driver.m, is provided as an example of processing 4 seismograms contained in the /data directory.

3. The /Help directory contains a set of web pages that can be accessed with a web browser or from the BCseis GUI.  It contains detail and background on the functions of BCseis.

This software was developed with MatLab version R2017b. Anecdotally, a Memphis student using R2015b had problems that could be fixed with a small amount of reprogramming.

I recommend experimenting with the GUI to understand the signal processing involved before trying to use the inline function.
