All digital images in manuscripts considered for publication will be scrutinized for any indication of manipulation that is inconsistent with the following guidelines. Manipulation that violates these guidelines may result in delays in manuscript processing or rejection, or retraction of a published article:
- No specific feature within an image may be enhanced, obscured, moved, removed, or introduced.
- The grouping of images from different parts of the same gel, or from different gels, fields or exposures, must be made explicit by the arrangement of the figure and in figure legend.
- Adjustments of brightness, contrast or color balance may be acceptable if they are applied to every pixel in the image and as long as they do not obscure, eliminate or misrepresent any information present in the original, including the background. Non-linear adjustments (e.g. changes to gamma settings) must be disclosed in the figure legend.
Any questions raised during or after the peer review process will be referred to the Editor, who may request the original data from the author(s) for comparison with the prepared figures. If the original data cannot be produced, the manuscript may be rejected or, in the case of a published article, retracted. Any case in which the manipulation affects the interpretation of the data will result in rejection or retraction. Cases of suspected misconduct will be reported to the author(s)’ institution(s).
