Importing PeakNet (Releases 4.3 through 5.2) Data Files

Overview

In order to use data files from PeakNet (releases 4.3 through 5.2) with Chromeleon, the files must first be imported into Chromeleon.

When the PeakNet 5 data file is imported, a Sequence for Chromeleon is created. The sequence includes the raw data from the data file, the embedded PeakNet 5 Method (converted to a Chromeleon PGM File and Quantification Method (QNT Method)), and additional information required to complete the sequence. If multiple data files are selected for import, they are grouped into one sequence.

If the PeakNet 5 data file contains multiple detectors, a separate sample line in the sequence is created for each detector (up to four).

How To

1. In the Browser, select a Datasource folder (not a sequence name).

2. On the File menu, point to Import/Restore, point to PeakNet 5, and click Data Files.

3. In the Import PeakNet 5 Data Files dialog box, browse for the folder that contains the PeakNet 5 data files to be imported. These files have a .dxd or .dxx file name extension (where xx is 01 - 99).

4. Select one or more data files and click Add. The files appear in the Selected files list.

5. The selected data files will be imported into the folder shown in the PeakNet Folder box. The default is the datasource folder currently selected in the Browser. To import the data file(s) into a different location, click the Browse button and select a location.

6. In the Sequence Name box, type a name for the sequence to be created from the imported data files.

7. Select the Inverted Curve Fitting check box to use inverted calibration (concentration or amount is plotted against measured values). Clear the check box for "normal" curve fitting (measured values are plotted against concentration or amount). See Calibrating  Inverting Dependent and Independent Variables for details.

8. Click Import.

The following files are created:

• One sequence, which contains a sample line for each PeakNet 5 data file selected for import. If any of the data files contained data from multiple detectors, separate sample lines are created for each detector's data.

• One Program File and one QNT File for each sample in the sequence. The Program and QNT Files are created from the PeakNet 5 Method embedded in the PeakNet 5 data file.

The PGM and QNT Files are named as follows: the Method file name from the PeakNet 5 data file is used, followed by a three-digit identifier that corresponds to the detector's position in the sequence, and then a .pgm or .qnt file name extension.

Example

In the Import PeakNet 5 Data Files dialog box, three data files are selected for import.

After importing, the following sequence is created. Notice that, because the Bioamine.d04 data file contained data from two detectors, two sample lines were created in the sequence:

The following Program and QNT Files were also created. These correspond to the programs and methods listed in the sequence:
