There are several ways to export data from-within database program.
It is possible to export experiment (measurement) or result (computed) data for individual data files. The export procedure is called from Measurement or Result forms through ‘Export’ button. User selects export file name and location; format is always CSV, i.e. text file with one column of (X,Y) pairs, values separated with comma, one pair per line.
A set of data can be exported at once, into one text file in CSV format. This export procedure is called from Diagram forms, through [File|Export CSV file…] menu command. Only data for active, displayed files is exported, in the order shown on the file list. The first line in the output file contains names of corresponding files in export order. Each name is enclosed in quotation marks, names are separated with commas. All other lines contain a series of values: (X,Y) pairs separated with commas, in the same file order as in the header line. As some files may be shorter than others, empty slots are left when necessary (i.e. there are separating commas present, but there is no value between them). Number of comma separated fields in each line throughout the file is constant.
The above mentioned export action is available for all 2D type of diagrams, regardless of data type.
Data formatting modes and display options listed below are taken into account when exporting data, i.e. data exported reflects data displayed, not the original source, unprocessed data:
o capacitance or concentration mode for CV displays,
o emission rate or time mode for Laplace spectra displays,
o XY mode for Laplace spectra displays.
Normalization of displayed data does NOT affect data exported.
Data for files excluded from final display (i.e. with names preceded with tilde ‘~’ on the file list) are omitted from export file.
Exporting peaks vs. something data
For peak displays, both in Laplace DLTS and conventional DLTS, it is possible to export data almost exactly in the same way as for 2D displays: using [File|Export CSV file…] menu command. The difference is that there is always only one data column with (X,Y) pairs and there is only one string item in the first, header line. This line contains comma separated names of the files the peak data is taken from. The whole string is enclosed in quotation marks.
The same rules as for 2D diagrams apply:
o data exported reflects data selected for display, for both X and Y axes,
o data for excluded points is not exported.
For peak displays it is also possible to export data in format compatible with TrapView (version 3.0) program. This action is invoked through either of two toolbar buttons: ‘Write TrapView-like peak file’ and ‘Export TrapView temporary peak file’. The first one allows to select both kind of data exported as well as file name, the second writes temporary file named data_tmp.pek, with standard TrapView compatible contents, to be used to exchange data with TV.
