TextImp: Text Import Module

The TextImp module supports waveform data to be imported from a text file. Various text file formats like comma separated values, tab separated values and other formats are supported. The TextImp module supports the graphical user interface as explained below.

Graphical Interface

To import from a file, enter the full path & name of the file in the File Name Textbox or click on Browse Button to select it.

File Name [Textbox]

Enter path & name of a valid waveform file to import in the File Name Textbox. Alternatively, click on browse to select an existing waveform file to import.

Browse [Button]

Click on the Browse Button to select an existing waveform file to import. Alternatively, enter path & name of a valid waveform file to import in the File Name Box.

Y-Axis Only [Option]

Select the Y-Axis Only Option if the text file to be imported contains Y-Axis data only.

Both X & Y-Axis [Option]

Select the Both X & Y-Axis Option if the text file to be imported contains both X-Axis and Y-Axis data. Note that X-Axis data needs to be followed by Y-Axis data, i.e. X-Axis data needs to be in first row or column and Y-Axis data in second row or column.

Row [Option]

Select the Row Option if data for an axis is in a single line. For example, a file may contain both X-Axis & Y-Axis. You should select this option if X-Axis values are in the first line separated by commas and then the Y-Axis values are in the second line separated by commas.

Column [Option]

Select the Column Option if data for an axis is organized vertically. For example, in a file containing both X-Axis & Y-Axis, each line should have one X-value and one Y-value.

Column Separator [Textbox]

Define how values are separated in a row.

Skip First n Lines [Textbox]

If the text file has a header or other information, enter how many lines of non-data information should be skipped.

Skip First n Values [Textbox]

After the importer skips the specified number of lines, it will skip n number of values

Horizontal Multiplier [Textbox]

If the input file has only Y-Axis values, then the horizontal multiplier is the inverse of sample rate, i.e. time duration of each data point. If the input file has both X & Y-Axis, then the X-Axis values are multiplied with this factor.

More [Checkbox]

Marking the More Checkbox shows more advanced options.

Horizontal Offset (s) [Textbox]

Enter horizontal offset in seconds. If Additive is unchecked, the entered horizontal offset is absolute and is the horizontal offset for the first point in the waveform, i.e. it overrides the horizontal offset inherent in the waveform. If Additive is checked, the entered horizontal offset is additive to any horizontal offset inherent in the waveform.

Additive [Checkbox]

Marking the Additive checkbox makes the entered horizontal offset as additive to the horizontal offset inherent in the waveform. Unmarking the Additive Checkbox makes the entered horizontal offset as absolute and is the horizontal offset for the first point in the waveform, i.e. it overrides the horizontal offset inherent in the waveform.
