An error about filename in I4DVAR

I'm running the I4DVAR for my real application. There is an error which is related to the netcdf filename. I'm comfused about this.
My ROMS version is 4.0, which is the newest one. The assimilation process runs pretty well. However, it says that "unable to open existing file". I have checked the directory. The netcdf filename is "YS_adj_outer2", which isn't the "YS_adj_outer2_001".
My question is whether there is some errors in the source code. How to change the wrong filename to correct one.

Code: Select all

 <<<< Conjugate Gradient Algorithm >>>>
