Next: Device Selection Up: The Sardana NeXus Recorder Previous: The Sardana NeXus Recorder Contents Index
We assume that Sardana has been setup properly to produce .fio files. To enable NeXus file creation, the ScanFile variable has to set:
p09/door/haso107d1.01 [8]: senv ScanFile '["tst.fio", "tst.nxs"]'
Then we have to check whether all required User Data are available:
p09/door/haso107d1.01 [14]: lsprof
Profile (MntGrp): mg_tk1
-------------------------- -------------------------------
Timer(s) d1_t01
Detector Components d1_c01, d1_c02, d1_mca01
Descriptive Components chi, slit1, beamline
Mandatory Components default
User Data {}
AppendEntry False
SelectorServer p09/nxsrecselector/haso107d1
ConfigServer p09/nxsconfigserver/haso107d1
WriterServer p09/nxsdatawriter/haso107d1
Profile is not set by nxselector(nxsmacros) or MntGrp has been changed
An error occurred while running Macro 'lsprof() -> eef330ba-2c91-11e6-be3c-901b0e39aa90':
Exception: User Data not defined ['beamtime_id', 'chemical_formula', 'sample_name', 'title']
In this example beamtime_id, chemical_formula, sample_name and title have to be supplied:
p09/door/haso107d1.01 [15]: nxsetudata beamtime_id 12345 An error occurred while running Macro 'nxsetudata(beamtime_id, 12345) -> 4f7941c2-2c92-11e6-be3c-901b0e39aa90': Exception: User Data not defined ['chemical_formula', 'sample_name', 'title'] p09/door/haso107d1.01 [16]: nxsetudata chemical_formula h2o ... p09/door/haso107d1.01 [17]: nxsetudata sample_name ice ... p09/door/haso107d1.01 [18]: nxsetudata title water
The command nxsresetdesc resets the descriptive components to those mentioned in the DefaultPreselectedComponents property of the NXSRecSelector server and it validates the selection: components depending on Tango servers which are not exported are removed.
p09/door/haso107d1.01 [15]: nxsresetdesc
Validation can also be done by:
p09/door/haso107d1.01 [15]: nxsupdatedesc
Now everything is prepared to generate NeXus output:

The device selection can be changed by a dedicated GUI, see 9.2, or by command:
