Hi; I have a question regarding roms.in. I have followed the instructions and I have all the files prepared but when I launch the roms, I get this error..I have tried to search for it but I can’t find it, could you send me the modis.in file for this example.  
Thank you and sorry for the inconvenience.

Does it work if you add these lines manually to roms.in ?

```julia
NBCFILES == 1
NCLMFILES == 1

```

They correspond to the number of files with boundary conditions and climatology data.
