Hi Jason,

Sorry for the inconveniance!

We've been changing some of the file naming conventions for MNC.  Please
rename your files so that you have:

  pickup.0000004000.0000.000001.nc  -->  pickup.0000.000001.nc
  pickup.0000004000.0000.000002.nc  -->  pickup.0000.000002.nc
  pickup.0000004000.0000.000003.nc  -->  pickup.0000.000003.nc
  ...

and that will, for the time being, solve the problem.

And, just to warn you, the above will probably change one more time as
we figure out a better way to deal with inherent netCDF file size limits
and our naming conventions (eg. having a "sequence number").
