6 -**//QuickNII//** enable the registeration of the brain section images to the reference atlas to generate atlas maps that are customised to match the cutting plane and proportions of the sections. The adjusted are done by linear transformation only to allow angles to be calculated.
5 +The QUINT workflow allows you to register series of histological section images from the brain to a 3D reference atlas such as the Allen Mouse Brain Atlas or the Waxholm Space atlas of the rat brain. This is a two-step process:

16 -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.
14 +Before you get started with image registration, make sure your images are the right size, and files are named according to the QUINT naming convention. See [[2. Image pre-processing with Nutil Transform>>2. Image pre-processing with Nutil Transform]] for details.

18 -(% style="color:#4e5f70" %)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).
