5 +Resize your raw 2D images to 24-bit PNG and JPEG. Images can be loaded up to the resolution of 16 megapixels (e.g.4000x4000 or 5000x3000 pixels), however QuickNII does not benefit from image resolutions exceeding the resolution of the monitor in use.

6 ->This is a quote. You can add a quote by selecting some text and clicking the quote button in the editor.
7 +The resized files must follow the naming convention having an unique ID in the format: sXXX.., with XXX.. reflecting the serial order and spacing of the sections (e.g. s002, s006, s010 for every 4^^th^^ section starting with section 2).

11 +Use the small program “FileBuilder.bat” provided with QuickNII. A new window will open, and ask for the folder where your images are located. Point to the correct folder, mark all image files, and click ok. An XML file is generated. Always save this file in the same folder as the resized images.

19 +>The idea is to determine the cutting angles (dorso-ventral and medio-lateral) for the whole serie as these should be consistant. Once found in a few sections, apply the same angles to the whole serie.

20 -Code blocks can be added by using the code macro:
21 +**The basic steps are:**
21 21  
22 -{{code language="python"}}
23 -x = 1
24 -if x == 1:
25 - # indented four spaces
26 - print("x is 1.")
27 -{{/code}}
23 +- (% style="color:#000000" %)Open one image in the beginning of the series and use anatomical landmarks to find the approximate anteroposterior position of the section.     Select the atlas modality to be overlayed to the image (MRI, Atlas, etc..)

25 +- **The transparency slider** can be used continuously to determine how well the atlas fits the section. Determine the sectioning angles (dorso-ventral and medio-lateral) by tilting the atlas and adjust the atlas borders.
26 +
27 +- Save the positions for this section for now, you can adjust these later.
28 +
29 +- Open the next image, located at the other end of the serie and repeat the same procedure as above i.e. (% style="color:#000000" %)find the approximate anteroposterior position of the section and test how well the cutting angles fit this section. Save the positions.
30 +
31 +(% style="color:#000000" %)- Explore a few sections in order to find the angles fitting most sections in order to achieve a global anchoring.
