# AMOR Data Storage

Data files at AMOR are stored in NeXus format, based on HDF-5. This is a portable binary format. For more information see the NeXus WWW-pages. Data storage happens normally without user intervention during scans or after a count command has finished. A couple of things are noteworthy, however:

- Data Storage in TOF-mode may take several minutes due to the amount of data to transfer. In this time the SICS server will be quite unresponsive.
- Data file writing can be interrupted. This is a unique feature at AMOR. As a consequence, a data file is NOT automaticaly created when a measurement has been interrupted.
- Data file writing can be forced by typing: storeamor.
- Data files can be found in directories: /home/AMOR/data/YYYY on the instrument computer or (after a litlle delay) at /data/lnslib/data/AMOR/YYYY . The YYYY is a placeholder for the year of data collection.
- The last data file written can be overwritten with command: killfile. Managers privilege is required for this command.

In order to have complete information in the data files a couple of SICS variables have to be set manually. A SICS variable's value can be interrogated by typing the name of the variable, and set by typing the name of the variable followed by the new value. The following variables are relevant:

user
  User name
email
  User e-mail address.
fax
  User fax number
phone
  User phone number
adress
  User address.
sample
  Sample name.
title
  Measurement title
