Data and Export

Viewing data in the BioSigRZ plots and worksheet.

History Plot

In averaging mode, BioSigRZ acquires data and calculates a running average. Data will be acquired until enough records have been gathered to compute the final averaged signal. At that time, the averaged signal will be appended to the end of the History Plot, the SGI will be incremented, a new stimulus signal will be generated according to the current stimulus parameters, and a new average will be computed. This process continues until the termination of the stimulus schedule is reached or until you manually end data averaging. Information about each SGI is displayed to the left of the history plot (pictured below). Right-clicking this data allows you to control what data is shown.

The Worksheet

The worksheet provides you with several basic functions. It allows you to graphically organize acquired data and perform mathematical and visualization manipulations of the acquired data directly in BioSigRZ. The Worksheet is located to the right of the History plot. Waveforms can be copied from the Worksheet and pasted to other applications for report writing or by choosing to generate a report, you may output data for use by other applications.

To place History Plot records into the Worksheet:

  1. Select the desired record(s).

  2. Click and drag the selected record(s) from the History Plot to the Worksheet.

The selected History Plot record(s) will be copied to the Worksheet.

Export Data

BioSigRZ has many on-board tools for viewing and working with responses. Records may be exported to an ASCII text file (.txt file) or CSV (spreadsheet) file or you can choose to do further analysis in an environment such as MATLAB. We can provide support for exporting data to the desired format, but we leave further analysis up to you so that you can do it your way.

To export to ASCII:

  1. Select the desired records in the History plot.

    Or to export all records in the History plot, click the label area at the top of the plot to clear all selections. When no records are selected, BioSigRZ will prompt to determine if all records should be exported.

  2. On the Menu bar, click the History menu and click Export to ASCII file.

  3. You will be prompted to supply the export file name and location where the file will be saved.

  4. Click Open.

    The selected records will be saved to the new file.

To export to CSV:

  1. Select the desired records in the History plot.

  2. On the Menu bar, click the History menu and click Export to CSV.

    To export the trace data, check the box next to Data Samples. If you wish to further customize the export, click the check boxes or radio buttons to toggle on/off the desired options. The settings shown are the typical/ recommended export settings.

  3. Type a report title in the Title field.

  4. Click the Generate Report button.

  5. When prompted, specify a file name and location to store the export file and click the Save button.

  6. When you are returned to the CSV File Export dialog box, you can change options and generate additional report exports or click Done to exit.

See the BioSigRZ Manual for further information on data viewing tools and export features.
