Figure 2

Visualization options provided by the ZcorrectorGUI. The data set consists of 56 images. Each image contained 256×256 pixels and was 86×86 μm2 in size. (A) An image of the m/z 58+ signals from a corrected data set of a single NIH/3T3 fibroblast. (B) The same data from A, after smoothing. (C–G) A series of corrected XY images of the m/z 58+peak intensities. With the corrected data, one can move through the cell vertically in a similar fashion as a CT scan moves through tissue. C is at the top of the cell, while G is near the bottom of the cell.
