Looks like a problem with your file.
Can you try:
od -a scala_protein_3_001_180.mtz | head
If your file is an mtz file, you should get output starting a bit like this:
0000000 M T Z sp ! o etx nul D A nul nul nul nul nul nul
If that is OK, then try:
strings scala_protein_3_001_180.mtz | tail -1
If you file has not be truncated, you should see the full MTZ headers of
the file.
