# Project settings For anything in this page, head to **AI Projects** -> **Your Project Name** -> **Project Settings**. This is not to be confused with general settings on the bottom of the sidebar. On this screen, you can change the project name, description, tile size, and even delete a project. You can also change the Featured Project Image and Channel settings, explained below. ### Changing the Featured Project Image The Featured Project Image dictates the thumbnail that will be auto selected for visual purposes when choosing an AI model. You can change this to whatever base image you would like by clicking the filename in the dotted box, and choosing an image to swap to ### Changing Project Channel Settings You must configure project channel settings if you have images with > 3 channels. You can also configure just to change brightness/contrast settings. Biodock supports up to 7 channels using psuedocoloring, but generally performance is best with 3 channels or fewer, unless your channels are sparse. You should choose only the most essential channels needed to identify your objects of interest.
{% hint style="info" %} Note that even if you only choose 3 channels here, you will still be able to quantify intensity across up to 100 channels! These channels are only for segmentation. {% endhint %} Use the Add channel button to name your channels and choose the color with which to represent them. At analysis time, you can map input images to these channels, even if they aren't in the right order. You can also choose brightness and contrast adjustments, per channel, that will apply across every image in the project, as well as at analysis time. If you have significant variation, it's best to be conservative with these adjustments. You can also make adjustments to project channel settings, or define custom settings per size group, in the [Labeling UI](https://docs.biodock.ai/start/path-2-train-a-fully-automated-ai-model/label-and-train#channel-settings). #### Channels: In Biodock, a channel represents a single layer of image intensity data corresponding to a specific signal, such as a stain, marker, or wavelength. Each channel can be visualized as a grayscale image, where intensity reflects signal strength. Multiple channels can be combined and color-mapped (e.g., RGB) to form composite images for analyzing multiple signals simultaneously. Before uploading to Biodock, you should check how many channels your images contain and what each channel represents. Most color images have three channels (Red, Green, Blue), while grayscale images, such as those from electron microscopy, typically have a single channel. In immunofluorescence images, each channel usually corresponds to a specific biological marker. In some cases, an image may technically contain three channels, but only one carries signal while the others are empty, making it effectively a single-channel image. Biodock can process all of these image types; however, before training a model or analyzing images, users should confirm that channels are correctly interpreted and correspond to the expected signals.
