GasPedal Changelog

The user benefits are described in the What's New document.

GasPedal 1.1

1.1.2 Final 01 (201907151540)

  • Fixed a problem where invalid time offset or modulation period values were accepted and applied for image computation.
  • Fixed a problem with spotdrift by using a computed effective modulation period based on the given modulation period if applicable.
  • Fixed a problem, where pressing the info (help) button on certain dialogs in the analysis component did not take any effect.
  • Fixed an occuring NPE if opening an empty project with a q-table column visibility file.
  • Quantitation tables for multiple images now close automatically only if the contained images are no longer in the project or have lost their spots.

1.1.1 Final 01 (201904262328)


  • The labels and the group ratio columns of the Quantitation Table can now be controlled in the Visibility Dialog (button with the eye).
  • Determining the Ratio Master Group for Statistics Tables has become more transparent:
    Before, the group on the top most position in the Project Manager was used as the reference for the group ratios in the Statistics Tables. To use a different group as reference, you had to move that one up to be on the top most position in the Project Manager.
    Now the Ratio Master Group follows the Ratio Master Image: the group containing the Ratio Master Image set in the Visibility Dialog (again: button with the eye) is also used as Ratio Master Group for the Statistics Tables.


  • The visibility of columns of your table is now saved along with your project, so that you can now use independent visability settings for different projects. Before it was a user setting, where you had to change the visible columns every time when changing the project if you had different demands in your projects.


  • The titles of the spot tables now better express which spots of which gel images they show.
  • Small problems with the enabled state of the buttons in the Visibility Dialog (the one with the eye ...) are solved.
  • Debug + Audit: added info about image size and warping problems to debug output and removed superfluous other info.

1.1.0 Final 02 (201811202254)


  • The manual is now up to date.
  • Accuracy when calculating fusion images has been increased.
  • Your choices on which attribute and group measures the statistics table should be based on are now saved.
  • You can now choose whether or not you want to apply calibration on calculating fused images.
  • GasPedal can now import data files directly into your project, is able to recognize known samples (list of samples visible in 'Images -> image Attributes...' in file names of imported files, to create / rename groups according to the samples recognized, and to sort images into the respective groups.
  • Importing images now first shows images already imported into your pool, but not yet used in the current project, and if there are none of these, opens the Import Wizard.
  • A new visualisation now shows at a glance in the Project Explorer, the Light Table and the Warping Setup, which sample, gel and channel are assigned to your images. And when pointing on this visualisation, a tool tip tells you details.
  • The job manager now shows automatically if you create jobs by defining automatic warps for the first time in the session.
  • The progress of an autowarp job now shows even if the job was started implicitely by clicking on "Warp" or "Find Match Vectors" in the Dual View.
  • Now you can change the warp mode also in the context menu if exactly two images are selected in the Project Explorer.
  • When clicking on "Review" of one of your image pairs in the Work Flow pane, the Dual View now activates the match vector tool automatically.
  • A new column called "Labels" is available on every Quantitation Table and shows labels from ALL images of the current project, not only those being visible in the current table. With its filters you can control the labels of which images you want to see or hide, regardless of the visibility status of the images themselves, and also regardless of whether the spots of these images are included in the total spot set or not.
  • On spots having labels also on matching spots on other images, the labels are now sorted corresponding to the sorting of the images of their origin in the project manager. This way, by moving the images up or down in the project manager, you can control their sequence in the combo box of the table rows yourself.
  • A new report, "", was included to enable in case of problems also end users to create debugging output, which can be saved and sent via email to
    When GasPedal is running, it can be produced by clicking on the link:
    Please use your browser function (press the keys CTRL + S simultaneously on your keyboard) to save the report.
  • Administrators in regulated environments, where e.g. CFR-compliance is relevant, can now benefit from syslog based audit trails.



  • If you defined filters in the Quantitation Tables, the report now applies these first, and uses its own defineable filters if not.
  • The report now validates your project setup on calculating results, and tells you, if something is not as it should be.
  • You now have the option to only show image pairs with the same gel.



  • A problem with the overlay rollup was fixed, where switching back to automatical visibility of spot or label layers did not always work.
  • Several rarely occuring NPEs were fixed.
  • Small cosmetical issues, typos etc. were corrected.
  • The native look-and-feel under Mac OS X was recovered by updating the involved libraries.
  • The job manager now refreshes more accurately and empties and populates its list and controls accordingly when closing and opening projects or the complete application.
  • When clicking on the status button in the Dual View and an image pair with automatic warping is opened, where the match vectors are not yet calculated, GasPedal now does not start finding match vectors any more.
  • A deadlock could occur on importing images.
  • Some problems with the workflow links to open images etc. have been fixed.
  • Some problems with calibration curves are now fixed, e.g. they are now deleted together with their image.

Note: version 1.1.0 Final 1 was not released.

  • On importing data, the modulation period now can be specified with up to 10 decimal places.
  • Fixed a problem in the "Image and Table Column Visibility", where the header check box already was checked, if any box in that column was checked. Now it will only be checked, if all rows in that column are checked.
