Cannot read tide files from otps2frc_v5.m

[outman]

helllo everyone
I use the otps2frc_v5.m(https://www.myroms.org/wiki/Tidal_Forcing) to create a forcing file
error shows:
NETCDF_OPEN - unable to open existing NetCDF file:
./input/tidetest.nc
call from: inp_par.F,find_file

I'm sure the tide file is existing.
