#------ Load libraries ---------
library(rmarkdown)
library(WGCNA)
library(DT)
library(htmltools)
library(ggplot2)


#----- 1. create the report directory ------------------------
system(paste0('mkdir -p ', opt$wgcna_construct_network_dir))


#----- 2. generate Rmd files with Rmd templates --------------
#   a. templates without placeholder variables:
#         copy templates from tool directory to the working directory.
#   b. templates with placeholder variables:
#         substitute variables with user input values and place them in the working directory.


#----- 01 wgcna_construct_network.Rmd -----------------------

#-------4. manipulate outputs -----------------------------
