Rosa (version 0.7.7)

Rosa--Regulon Structure-based Activity inference

version 0.7.7

The statsitical model of Rosa

Rosa performs regulon structure-based activity inference, a statistical model for quantitative inference of protein activities using gene regulatory networks reverse-engineered from scRNA-seq. Rosa calculates a normalized enrichment score (NES) that represents the protein activities of the candidate regulators. Rosa is inspired by Viper, a popular R package developed by Dr. Andrea Califano’s Lab.

The network-based inference framework

Step 1

Run ARACNe/ARACNe-AP, which was developed by Dr. Andrea Califano's lab.

Step 2

Run Rosa.
