In the other package vignettes, usage of ceRNAnetsim is explained in details. But in this vignette, some of commands which facitate to use of other vignettes.

#ACTB: interacts with various miRNA in dataset, so ACTB is not isolated node in network and increases to 1.87-fold.Firstly, clean dataset as individual gene has one expression value. And then filter genes which have expression values greater than 10.

group_by(Target) %>%

ungroup() -> TCGA_E9_A1N5_mirnagene
TCGA_E9_A1N5_mirnagene%>%
filter(gene_expression > 10)->TCGA_E9_A1N5_mirnageneWe can determine perturbation efficiency of an element on entire network as following:
TCGA_E9_A1N5_mirnagene %>%
priming_graph(competing_count = gene_expression,
miRNA_count = total_read)%>%
calc_perturbation(node_name= "ACTB", cycle=10, how= 1.87,limit = 0.1)On the other hand, the perturbation eficiency of ATCB gene is higher, when this gene is regulated with 30-fold upregulation like in HIST1H3H.
