FOCUS Data Storage

FOCUS writes data into portable binary NeXus files. The scheme implemented involves opening a new file for any run and updating this file at predefined intervalls during counting operations. All this is commonly handled automatically by the count command. However, data file writing can be initiated and configured manually from the command line through the following commands:

storefocus start

Write a new data file

storefocus update

Updates the current data file.

storefocus intervall

prints the current update intervall to use during counting. Units is minutes.

storefocus intervall newval

Sets the update intervall to newval minutes.

killfile

This command will overwrite the last data file written and thus effectively erase it. Therefore this command requires manager privilege.
