Hello,

I am having trouble with the code below.

   LandMask = hdfread(MOD03, '/MODIS_Swath_Type_GEO/Data Fields/Land/SeaMask', 'Index', {[1  1],[1  1],[X  Y]});

The problem is that the name of the data field is "Land/SeaMask" in other words, the forward slash is in the name itself. Matlab is trying to find "SeaMask" which does not exist.

Thanks.

It is not possible to have a forward slash in a file name in any Unix-like operating system including OS-X and Linux. Forward slash is always the directory separator in such systems.

According to http://blogs.msdn.com/b/larryosterman/archive/2005/06/24/432386.aspx, in MS Windows, forward slash and backwards slash are equivalent in the operating system and always have been. Therefore you cannot have a forward slash in an MS Windows filename either.
