Problem when dealing with the boundary file of tidal forcing

[zhaoqian]

When I use the matlab code "otps2frc_v3.m" to generate the nc file of tidal forcing, some mistake occurs. I am so confused .Please help me!
The OS of my computer is Suselinux 10.1, the matlab R14(sp2) and the netcdf for it are installed.
