5.6.4. Sample templates

| top | pdf |

The construction of CBF/imgCIF files can be simplified using templates. A template is itself an imgCIF file populated with data entries but without any binary sections. This file is normally associated with a CBF handle using the cbf_read_template call and provides a framework into which images and other experiment-specific data may be entered.

Fig.[link] is a sample template for an ADSC Quantum 4 detector (ADSC, 1997[link]) with a κ-geometry diffractometer at Stanford Synchrotron Radiation Laboratory (SSRL) beamline 1–5.

Template imgCIF for use with an ADSC Quantum 4 detector.

The template for a MAR345 image plate detector (MAR Research, 1997[link]) is almost identical. The major differences are in the size of the array (2300 × 2300 versus 2304 × 2304), the parameters for the CCD elements and the geometry of the elements. Therefore a few of the values in the AXIS, ARRAY_STRUCTURE_LIST, ARRAY_STRUCTURE_LIST_AXIS and ARRAY_INTENSITIES categories are different, as listed in Fig.[link].
