applying ww3_grid.inp file to a global bathemetry set

[JMSnyder1980]

I have a ww3_grid.inp file that works perfectly with output boundary conditiions which is attached
ww3_grid.inp.txt.

This is all good but how to I apply this to other bathemetry condtions? For instance I have the following global bathemetry data files that I want this ww3_grid.inp to work with which are attached here:
global_1p0_mask_new.dat.txt
global_1p0_obst_new.dat.txt
global_1p0_bathy_new.dat.txt

When I run the original ww3_grid.inp that is attached the file runs perfectly with output boundary conditions shown. However when I try to modify this file to process the global bathemetry files attached I get an error? How do I modify the ww3_grid.inp file to successfully process the above global bathemetry files with the output boundary conditions? The bathemetry filses cover longitude 0 to 360 degrees longitude and -78 to 80 degrees latitude? The error I get is the following:

Output boundary points :

*** WAVEWATCH III ERROR IN W3GRID :
ERROR IN READING FROM INPUT FILE
IOSTAT = 0
