Hi

To me this sounds like a little-endian/big-endian problem. I guess you use
Linux on a Intel-processor which is little endian, opposite to SGI which is
big endian. If you read your data in binary form as integer or long, this
could be the clue to the problem. Then the you should either use a platform
independent data storage (XDR, HDF, netCDF) or you could swap the bytes with
the BYTEORDER procedure (check the documentation for the appropriate
keywords).

Probably this will help

Cheers

Martin
