exFINDER is a method that identifies external signals (received signals from the external system) in the single-cell transcriptomics datasets by utilizing the prior knowledge of signaling pathways. Specifically,exFINDER contains the following features:
- It develops a computational method that links the prior knowledge and scRNA-seq data to identify the external signals received by the cells.
- It uses a computational model that utilizes the graph theory to infer the external signal-target signaling networks (exSigNet) and link the expression data to signaling strength.
- It provides multiple ways for visualization and analysis of the external signal-target signaling networks (exSigNet).
exFINDER R package can be easily installed from Github using devtools (it may take a little while):
devtools::install_github("ChanghanGitHub/exFINDER")
