Hello,

I'm unfamiliar with smfl, and it doesn't appear that you're working with any 
netCDF data, so I'm afraid there isn't I can do for you.  I might suggest 
trying the appropriate stack overflow community resource.

Sorry this isn't more immediately useful, but I'm afraid I would need to solve 
this issue myself before I was able to provide you any guidance.
