Integrated step-by-step vignettes present on the wiki.
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.
