A MATLAB script to allow manually pick P wave arrival and the first motion. There are generally three functions of the script:
1. To judge whether the signal is an AE waveform or a noise.
2. To visualize the P wave arrival automatically picked by the AIC picker (Akaike, 1998) and the first motion.
3. To calculate the DD value (Maeda, 1985) which indicates the the certainty of P wave picking
4. To manually adjust P wave arrival and fist motion.
