-These files including three main parts:
-
-- **Preprocess pipeline** (*etc. bulkRNA, bulkATAC, ChIP, WGBS ...*)
-
-	These R scripts are designed to generate a directory tree containing ordered directories for intermediate data and Linux bash scripts for each step.
-	In convenient to submit jobs to different nodes of a computer cluster at same time, commands for multiple samples can be divided to several batches and than submit together.
-
-- **Downstream analysis script** (*etc. DEG, GO, GSEA ...*)
-
-	These scripts are the framework of different analyses designed to cope with the most simple scene of biology analysis.
-
-- **Visualization script** (*etc. heatmap, PCA plot, Venn plot, track plot ...*)
-
-	These scripts can generate some plots suitable for articles with very few post processing.
