Scissor is an innovative approach that helps researchers identify specific cell subpopulations from single-cell data by utilizing bulk sample phenotypes such as disease stage, tumor metastasis, treatment response, and survival outcomes. In this article, we’ll walk you through how to install and utilize Scissor effectively to enhance your research outcomes.

Installation of Scissor

Before diving into Scissor, you need to ensure that you have the appropriate prerequisites installed, which include R and the Seurat package. Follow the steps below to get started:

• Ensure you have R version 3.6.1 installed.
• Install the Seurat package by running the following command within your R terminal:

  install.packages("Seurat")

• Install Scissor by executing:

  devtools::install_github("sunduanchen/Scissor")

Utilizing Scissor

Scissor operates by correlating bulk sample data with single-cell sequencing data. This allows you to identify highly phenotype-associated cell subpopulations effectively. Let’s use an analogy to explain this process:

Imagine you are a chef tasked with crafting a signature dish. You have a pantry full of ingredients (your bulk sample data) and a group of taste testers (your single-cell data). By mixing various ingredients and observing the feedback from your testers after each tasting (correlating data), you can refine your recipe to create a dish that resonates best with your audience (identifying cell subpopulations). Just like adjusting flavors based on feedback, Scissor helps you refine your analysis based on phenotype associations.
