|
|
|
9 This pipeline has been founded by IBISA-APLIBIO(http://www.renabi.fr/platforms/aplibio/),
|
|
|
10 and has been built by (1)Yufei Luo, (2)Marie-Agnès Dillies, (1)Matthias Zytnicki and (1)Delphine Steinbach.
|
|
|
11 (1): Bioinformatics plateform URGI, INRA URGI Versailles, France
|
|
|
12 (2): Plate-forme Transcriptome et Epigenome, Génopole, Institut Pasteur, France

|
|
|
15 This pipeline performs differential expression analysis on two different conditions with arbitrary number of replicates.
|
|
|
16
|
|
|
17 One reference genome (fasta format), one annotation (gtf format) and several RNA-seq samples are required.
|
|
|
18 Step 0: Upload RNA-seq samples.
|
|
|
19 Step 1: Clean the annotation file.
|
|
|
20 Step 2: Clean the RNA-seq files.
|
|
|
21 Step 3: Map the RNA-seq samples to the genome reference, using Tophat.
|
|
|
22 Step 4: Convert the bam files (given by Tophat) to sam files.
|
|
|
23 Step 5: Count the reads per annotation using S-MART (CompareOverlapping).
|
|
|
24 Step 6: Build the input files for DESeq.
|
|
|
25 Step 7: Differential expression analysis using DESeq, and output graphical results.

30 Instructions
|
|
|
31 ------------
|
|
|
32 Environment Installation:
|
|
|
33 0). First, download and install S-MART (eg from Galaxy Tool Shed: http://toolshed.g2.bx.psu.edu/repos/yufei-luo/s_mart).
|
|
|
34 1). Download and put the pipeline scripts directory under the S-MART directory
|
|
|
35 (ex. mv DiffExpAnal /home/user/galaxy-dist/tools/s_mart/SMART/.).

|
|
|
38 * R, under the GNU General Public License (at least 2.14.1 version).
|
|
|
39 * Python, under the Python License, compatible with the GNU General Public License (better 2.7)
|
|

40 * S-MART (http://urgi.versailles.inra.fr/Tools/S-Mart), a toolbox which handles mapped RNA-Seq and ChIP-Seq data.
|
|
|
41 * DESeq (http://bioconductor.org/packages/release/bioc/html/DESeq.html), an R package to analyse
|
|
|
42 count data from high-throughput sequencing assays such as RNA-Seq and test
|
|
|
43 for differential expression. The package is available via Bioconductor (http://www.bioconductor.org/)
|
|
|
44 and can be conveniently installed as follows:
|
|
|
45 Start an R session and type:
|
|
|
46 source("http://www.bioconductor.org/biocLite.R")
|
|
|
47 biocLite("DESeq")
|
|
|
48 * Biobase(http://www.bioconductor.org/packages/2.12/bioc/html/Biobase.html), an
|
|
|
49 Bioconductor package and can be installed as follows:
|
|
|
50 source("http://bioconductor.org/biocLite.R")
|
|
|
51 biocLite("Biobase")
