Action
- Set the Marks in DatLab on a selected (active) Plot.
- Go to the menue [Marks]/[Statistics]. A table is shown with all marks and their values.
- Select the O2k-chamber (A or B) for which plots should be displayed.
- Plot for marks: Select the source plot on which the relevant Marks are set.
- Channel selection: Select channels for which plots should be displayed in the mark statistics table.
- Copy to clipboard options: Select/deselect »Traceability in DatLab-Excel templatesa and »Experimental detailsa (see footnotes a and b for a summary).
- Select how the displayed values are calculated over the sections defined by marks. Default: Median; other options: Average, Range, Maximum, Minimum.
- Sort by: Select the sequence of marks, sorted according to a time sequence (Time) or in alphanumerical order (Mark name). Values are displayed for all selected plots. The source plot for marks is indicated by an "X".
- Copy to clipboard to copy the table with or without 'Experimental details' to another programme/file (Excel-DatLab templates). Open the target file (Excel-DatLab templates and paste [Ctr-V] into the yellow cell for the subsample as indicated.
- Footnote a: Traceability in DatLab-Excel templates is selected when copying Mark statistics from DatLab to DatLab-Excel templates for DatLab 7. The uncorrected negative slope of the calibrated oxygen concentration over time (O2 slope neg.) is shown in the Mark statistics table and copied to clipboard, together with 'Experimental details'. All corrections and normalization is performed in the DatLab-Excel templates, for traceability and quality control of the analysis. To copy the current values (e.g. flux per mass), the tick box Traceability in DatLab-Excel templates is deselected, when copying to older versions of DatLab-Excel templates or other programmes (e.g. SigmaPlot). It is important to carefully evaluate which set of data rows is relevant.
- Footnote b: Experimental details are copied to clipboard as default in DatLab 7, preceeding the table as shown in the Mark statistics window. This option is to be chosen for the new DatLab-Excel templates. In order to use older versions of DatLab-Excel templates, this function is switched off by deselecting the tick box 'Experimental details'.
