Whole Image Warping
Until now, experimental variation has been an unavoidable factor in analysis, which had to be accepted, then controlled. This convention no longer applies with Ettan Progenesis. Warping drives robust matching. Whole image warping allows accurate matching of images created under the most diverse of conditions.

Whole image warping in Ettan Progenesis uses every pixel in the image to calculate local warping requirements, thus ensuring the highest possible levels of reliability without losing genuine changes.

Shown below is a straightforward example of warping on gels run from the same microbial sample, after warping, the apparent chaos of the overlaid image is transformed to show a much clearer picture.

Image warping in action
Warping enables a variance in gel type that would previously not have been possible. Valid comparisons can be carried out between gels of different size, resolution and different staining techniques.

Shown below is an example of warping on gels of differing sizes. From left to right the gels can be seen overlaid, then warped and the final image shows vector lines that emphasise the dramatic differences that Ettan Progenesis can tolerate.

Panel (a) and (b) show 2D separation of the same sample run in different laboratories. Panel (c) shows the samples overlaid, a colour contrast of blue on yellow highlighting apparent differences. The second frame shows whole image warping applied where the grey colour indicates a match.
