# ComfyUI Spectral

`ComfyUI Spectral` is a ComfyUI custom nodes library based on the [spectral](https://github.com/spectralpython/spectral), 
mainly used for visual processing of spectral files

## Install

You can choose to install it using [ComfyUI Manager](https://github.com/ltdrdata/ComfyUI-Manager)

Or manual installation:

1. clone to your `custom_nodes` folder
2. `cd ComfyUI_Spectral`
