Extracting and Exporting Spectra, Chromatograms, and 3D Fields

Spectra

You can copy each spectrum extracted from a 3D field in the PPA method or on the spectra plot (see Integration  The Spectra Plot) to the Windows clipboard (Copy command). From the clipboard, you can then paste the spectrum in a spectra library (Paste command). (For information about spectra libraries, refer to Data Representation and Reprocessing  Spectra Libraries).

To copy a spectrum from the 3D field to the Windows clipboard

  1. Select Extract > LIB-Spectrum to clipboard on the View or context menu.

  2. Open an existing Spectra Library. Select the command by opening the corresponding LIB file from the Browser,
    - or -

    Select File> New > Spectra Library to create a new library.

  3. Select Paste Spectra to save the spectrum and the data in the library.

Chromatograms

From an open 3D field in the method PPA, you can extract a chromatogram of any wavelength.

To save the active chromatogram as a separate channel

  1. Select Extract > Chromatogram to file on the View or context menu.

  2. Select the wavelength and the bandwidth at which to extract the chromatogram.

Chromeleon will suggest a name for the extracted chromatogram, considering the wavelength. However, you may also enter any other name of your choice. The chromatogram is saved in addition to the raw data of the existing 3D field. Simultaneously, the extracted chromatogram is opened via the Integration method to give the user an overview of the saved data.

In addition, the Extract > Chromatogram to file command provides a special option. Instead of saving one single chromatogram, another chromatogram of the same wavelength can be extracted and saved from all samples of the underlying sequence or query. Enable Extract from all samples of current sequence or query.

3D Field Data

You can include and display 3D field raw data in other applications, such as Microsoft Excel. Data is converted into a general ASCII format.

To export 3D data to another application

  1. Select Export > 3DFIELD on the View or context menu.

  2. Change to the other application and insert the data, using the Paste command. In addition to the pure raw data, additional sample and sequence information is transferred to the application.
