AskoR is an R pipeline for gene expression analysis from RNAseq data. It allows, through the articulation of well-known R packages (EdgeR, UpSetR, topGO, Coseq), to perform a complete and automatic transcriptomic analysis: data filtering, normalisation of filtered data, descriptive analysis of data quality, differential gene expression analysis, enrichment in terms of "Gene Ontology", clustering genes by co-expression profile, and enhanced with multiple graphic representations.
You'll find a test set in the inst/extdata/input folder. It'll be used for the vignettes documentation.
- Count matrix file: CountsMatrix.txt OR Counts files per samples: files in "counts" directory (counts.tgz)
- Samples file: Samples_CountsMatrix.txt OR Samples_CountsFiles.txt
- Contrasts file: Contrasts.txt
- Genes annotations file: Genes_annotations.txt (optional)
- GO annotations file: GO_annotations.txt (optional)
IMPORTANT : All input files must be in a folder named input (case sensitive).
NOTE: Currently it is preferable to use this method which is the most up to date.
If you don't want to install it: You can use the AskoR.R file in ScriptR instead and "run file" in the same directory.
Just source it in your R script file (see AskoR_analysis_script.R):
source("/directory/where/you/downloaded/the/file/AskoR.R")
OR
NOTE: This method is not up to date, we will update it asap !
Download the latest development code of AskoR from GitHub using devtools with
install.packages("devtools")
library(devtools)
devtools::install_github("askomics/askoR")
For Windows users only: install Rtools or check that it is already installed (needed to build the package).
