2.4 | 36 | **Basic steps:** |
| |
1.1 | 37 | |
| |
10.1 | 38 | **//Nutil Quantifier//** quantifies and assigns anatomical location to labelled objects identified by segmentation in rodent brain section images (mouse or rat). |
| |
1.1 | 39 | |
| |
7.1 | 40 | It requires the following input: |
| |

19.2 | 42 | 1. (% style="color:#c0392b" %)**Segmentations with the labelling displayed in a single RGB colour** |
| |
7.1 | 43 | |
| |
2.4 | 44 | **Requirement:** |
| |
1.1 | 45 | |
| |
21.1 | 46 | * Input format: 24-bit RGB images in PNG |
| 47 | * The images have to have the same aspect ratio as the images used in QuickNII to generate the atlas maps (can be a different size). | ||
| 48 | * //Quantifier** **//is only able to extract one RGB colour at a time. Apply one RBG colour to all of the objects of interest, and specify this colour co//d//e in the GUI (e.g. 255, 0, 0 for red). | ||
| |
1.1 | 49 | |
| |
2.4 | 50 | To generate the segmentations we recommend the //Pixel and// //Object Classification workflows// in the //ilastik// software (//ilastik.org//). However, any image analysis software may be used. |

| 68 | * Waxholm Space Atlas of the Sprague Dawley rat brain v2 or v3. |
