Extract Irradiation Times from an XSYG-file

Extracts irradiation times, dose and times since last irradiation, from a Freiberg Instruments XSYG-file. These information can be further used to update an existing BINX-file.

manip, IO
extract_IrradiationTimes(object, file.BINX,
  recordType = c("irradiation (NA)", "IRSL (UVVIS)", "OSL (UVVIS)",
  "TL (UVVIS)"), compatibility.mode = TRUE, txtProgressBar = TRUE)

character, '>RLum.Analysis or list (required): path and file name of the XSYG file or an '>RLum.Analysis produced by the function read_XSYG2R; alternatively a list of '>RLum.Analysis can be provided.

Note: If an '>RLum.Analysis is used, any input for the arguments file.BINX and recordType will be ignored!


character (optional): path and file name of an existing BINX-file. If a file name is provided the file will be updated with the information from the XSYG file in the same folder as the original BINX-file.

Note: The XSYG and the BINX-file have to be originate from the same measurement!


character (with default): select relevant curves types from the XSYG file or '>RLum.Analysis object. As the XSYG-file format comprises much more information than usually needed for routine data analysis and allowed in the BINX-file format, only the relevant curves are selected by using the function get_RLum. The argument recordType works as described for this function.

Note: A wrong selection will causes a function error. Please change this argument only if you have reasons to do so.


logical (with default): this option is parsed only if a BIN/BINX file is produced and it will reset all position values to a max. value of 48, cf.write_R2BIN


logical (with default): enables TRUE or disables FALSE the progression bars during import and export


The function was written to compensate missing information in the BINX-file output of Freiberg Instruments lexsyg readers. As all information are available within the XSYG-file anyway, these information can be extracted and used for further analysis or/and to stored in a new BINX-file, which can be further used by other software, e.g., Analyst (Geoff Duller).

Typical application example: g-value estimation from fading measurements using the Analyst or any other self written script.

Beside the some simple data transformation steps the function applies the functions read_XSYG2R, read_BIN2R, write_R2BIN for data import and export.


An '>RLum.Results object is returned with the following structure:

.. $irr.times (data.frame)

If a BINX-file path and name is set, the output will be additionally transferred into a new BINX-file with the function name as suffix. For the output the path of the input BINX-file itself is used. Note that this will not work if the input object is a file path to an XSYG-file, instead of a link to only one file. In this case the argument input for file.BINX is ignored.

In the self call mode (input is a list of '>RLum.Analysis objects a list of '>RLum.Results is returned.


The produced output object contains still the irradiation steps to keep the output transparent. However, for the BINX-file export this steps are removed as the BINX-file format description does not allow irradiations as separat sequences steps.

BINX-file 'Time Since Irradiation' value differs from the table output?

The way the value 'Time Since Irradiation' is defined differs. In the BINX-file the 'Time Since Irradiation' is calculated as the 'Time Since Irradiation' plus the 'Irradiation Time'. The table output returns only the real 'Time Since Irradiation', i.e. time between the end of the irradiation and the next step.

Negative values for TIMESINCELAS.STEP?

Yes, this is possible and no bug, as in the XSYG-file multiple curves are stored for one step. Example: TL step may comprise three curves:

  • (a) counts vs. time,

  • (b) measured temperature vs. time and

  • (c) predefined temperature vs. time.

Three curves, but they are all belonging to one TL measurement step, but with regard to the time stamps this could produce negative values as the important function (read_XSYG2R) do not change the order of entries for one step towards a correct time order.
