POLDI Data Storage

POLDI 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:

storedata start

Write a new data file

storedata update

Updates the current data file.

storedata intervall

prints the current update intervall to use during counting. Units is minutes. Default is 20 minutes.

storedata 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.
