Handling Run Sequences


When running experiments on your instrument, you will be either creating new run sequences using custom or preprogrammed procedures or restoring a saved run sequence.

If you have the QNX/Platinum features installed, run sequences may be scheduled to run automatically. See Introducing Platinum for more details.


Select from the following topics for more information:

What is a Sequence File?

A sequence file (default extension is .seq) is made up of one or more run records (maximum of ten runs for non-Autosampler instruments and 65 runs for Autosamplers). Each run record is instrument mode based and contains the sample and procedure information. A sequence file may be saved for future recall and execution.

NOTE: Only Thermal Advantage for Q Series files are compatible with this software.

Types of Sequence Files

If your instrument is equipped with the latest Platinum/QNX software, there will be two types of  sequences available—Experiment or Calibration sequences.  Both types of sequences independently exist in the instrument. This allows you to set up and save a calibration sequence for future recall without affecting your experimental sequence.

To access these sequences, click on either the Experiment or Calibration   buttons at the bottom of the sequence pane.  The experimental sequence will allows the configuration of ten runs for non-Autosampler instruments or 65 runs for instruments with an Autosampler. The calibration sequence allow configuration of 10 runs.  

With either type of sequence, the configuration and execution is the same. See the remaining sections in this topic for more information regarding sequences.

NOTE:  If the calibration sequence is not applicable for you instrument, this feature is not available.

How Do I Create a Run Sequence?

From the Sequence Pane, select the tool bar button or right click and select New Sequence from the pop-up menu or Experimental/Sequence File/New from the menu to create a new sequence. When you choose this menu item you are prompted to save the current sequence file (if this confirmation option has been selected on the User Preferences/Confirmation Page). After saving the current sequence file, the old runs are erased and a single run record remains in the sequence. This run is actually a copy of the scheduled run.

At this point you can elect to edit the run using the tool bar buttons or menu. If you edit the run information, this will automatically reset the run status upon clicking on the Apply button.  If youíre planning to edit all the runs, you could also start another New Sequence.

How Do I Append a Run Sequence?

When you have completed editing the contents of the run, you can add more runs to the sequence by clicking the Copy and Append Run button on the Sequence Pane or by using the Sequence Pane's tool bar or pop-up menu (click here for more information). You can drag-and-drop runs to reorder the runs in a sequence.

How Do I Delete a Run Sequence?

To delete a run from the sequence, first click on the run number in the sequence list. Then select the Delete Run   button or select Delete from the sequence pop-up menu options. When you choose the menu item you are prompted to verify that you wish to delete the selected run.  Select Yes to delete the selected run or No to cancel operation.

How Can I Reset a Completed Run Sequence?

At the end of the sequence, a checkmark will appear next to the completed runs. You can reset the run by clicking on the arrow.  This action will reset the run status (check to standby) and automatically increment the file name.  Alternatively, you can edit the run information and this will automatically reset the run status upon clicking on the Apply button.

How Do I Save a Run Sequence?

After you have created, edited, and arranged the runs as desired, you can save the sequence file one of three ways:

The Save Current Sequence to File window will be displayed. Enter or locate the folder where you wish to store this sequence. Enter a sequence file name. Once all of the sequence run information is collected, press the Save button.

If you do not want to save the entire sequence, you can manually choose the runs to save. Highlight the desired runs to save on the Sequence Pane. (Hold down the CTRL button while selecting to allow multiple runs to be selected.) Right click to display the Sequence pop-up menu. Select Save Selected Runs Only.

How Do I Execute a Run Sequence?

Once the runs in your sequence have been set up and you are ready to begin the sequence, click next to the run # in the sequence list that you wish to begin the sequence.  The arrow will relocate next to this run. Select Start on the touch screen or on the instrument control tool bar to begin.

How Do I Restore an Existing Run Sequence?

To restore an existing run sequence so that you can run it again, simply click the button on the Sequence Pane or use Open Sequence on the pop-up menu to open a sequence (.seq) file. Then locate and open the desired sequence file. If there are any duplicate data filenames, they will be automatically changed so that no file conflicts occur. The Open a Sequence File window will be displayed. Verify that the sequence file (*.seq) is the selected file type. Select the desired file. A summary of the file is shown in the preview pane to the right.

When you open a sequence file it will replace the current sequence unless you use the New name scheme option. This allows you to open an existing sequence file that can be used as a "template" for a new sequence. Enter a new data file naming convention. This will be applied to all of the runs contained in the "template," creating a new sequence.

How Can I View a Sequence File?

If you want to view the contents of a sequence file, follow these directions:

  1. Select Tools/File/Utility from the main menu.

  2. Enter or locate the folder used to store your sequence files. Double click on a folder to open it.

  3. Select sequence (*.seq) files as the file type.

  4. Click on the desired sequence file to view. A summary of the sequence file is displayed containing each procedure and the sample information for each run in the sequence.
