38 -1. Open an image in the beginning of the series, and use anatomical landmarks to find the approximate anteroposterior position of the section in the atlas. Select the atlas modality to be overlaid on the image (MRI, Atlas, etc.)
39 -1. Tilt the atlas by adjusting the dorsoventral and mediolateral angles. Move the transparency slider back and forth to see how well the atlas fits the section. The size of the atlas slice can also be modified for a better fit.

41 -1. Open another image, located at the other end of the series, and repeat the same procedure as above:, i.e. find the approximate anteroposterior position of the section, and test how well the cutting angles fit this section. Save your settings.
42 -1. Explore a few sections throughout the series in order to and find the angles that fit most sections in order to achieve a good global anchoring. Ideally, the cutting angles should be consistent throughout the entire section series.
43 -1. Once two or more sections are anchored at their approximate position within the brain, QuickNII propagates the cutting angles across the entire image series. The anteroposterior position of the images is also estimated based on the section numbering.

42 +1. Explore a few sections throughout the series in order to and find the angles that fit most sections in order to achieve a **good global anchoring**. We recommend to keep the cutting angles consistent throughout the entire section series, unless two blocks were cut separately.
