Brief description of scripts involved.

1) create_tide_bc_4bdry.m 
Scripts to create tidal amplitude and phase boundary condition. 
The main script, need to use boundary grid file.
When using the script, need to modify the CAT directory.  

2) create_bc_grid.m 
Script to generate boundary grid file, lat, lon, AngleCS, AngleSN 
Use this one before use create_tide_bc_4bdry.m 
Need MITgcm domain file directory as input. 


3) tide_rot.m  
This script is used in create_tide_bc_4bdry.m 
Rotate uamp, upha, vamp and vpha to a new coordinate  

4) intp_line_safe.m  
A line interpololation scripts to make sure there 
is no NaN in tidal current amplitude and phase  

5) There are other scripts that come with CAT package.
