## Also we will use "ROR1.data" as query RNA-seq gene expression data. This data is for ocular lens epithelial cell differentiated from human pluripotent stem cells.
## These data sets are loaded automatically with the package.
## Pre-process the query data (ROR1.data), the data has already been made in CPM and log2 normalized format.
ROR1.processed.data<-preprocess_querydata(cell.tissue.data = ROR1.data, exp.cutoff.th = 1.8)
## Identify active pathway paths of the processed query data
ROR1.active.pathway<-identify_active_pathway_path(pathway.path = pathway.path, processed.query.data = ROR1.processed.data)
## Get active pathway ranking metric (i.e., activity score and number of downstream transcription factors)
ROR1.active.pathway.ranking.metric<-get_pathway_ranking_metric(active.pathway.path = ROR1.active.pathway, processed.query.data = ROR1.processed.data, high.exp.th = 7)
## Plot the ranking metric result (i.e., activity score and number of downstream transcription factors) in a 2D plane
display_pathway_ranking_metric(pathway.ranking.metric = ROR1.active.pathway.ranking.metric)
## To separate the top ranked pathways we can do this
abline(v=45, h=0.2, lty=2, col="black")
