Figure 4

Photographs of two neighboring cryosections prepared to be subjected to laser ablation and to histological analysis (A,B). The image C is the result of registering the images (A,B). The blue rectangle indicates in the images (A–C) the minimal rectangle (with sides parallel to axes) the image fits in. The red line in the image (A,C) accentuates orientation of the corresponding borders on both the images. Images (B,C) are compared in the image (D): while the places appearing in both images have black color, the space in blue corresponds to symmetric difference of both images as explained in Supplementary Note 1.
