Hi, just for fun and to demonstrate what can go horribly wrong if you blindly use utilities that were specifically designed for changing the line terminators in an ASCII file, I applied these utilities to an MTZ file.
First I used 'todos' to simulate what I suspect the technician has done: todos < original.mtz > original+todos.mtz Then I used 'tounix' in an attempt to recover the original file, as others have suggested: tounix < original+todos.mtz > original+todos+tounix.mtz What can possibly go wrong? The log files from mtzdump are attached - see for yourself! (the mtzdump on original+todos.mtz went into an infinite loop and I had to kill the process).
