Workflow Scripts for Processing large-scale Microarray datasets.

Scripts for quality control, MAS5 normalization, gene filtering and annotation are present in the src/qc, src/mas5, src/filter and src/annotation directories. A workflow for constructing a gene expression matrix is as follows:

1. Download the datsaets from GEO/ArrayExpress(AE) and organize them as follows: <EXP_DIR> is the root directory, in which all datasets are placed. Files are organized in the folders: <EXP_DIR>/CEL/<ACCESS_NAME_DIR>/<CEL_FILES>, where <ACCESS_NAME_DIR> is the accession id, under which the files were submitted in ArrayExpress (AE) or GEO.
2. Run Quality control using the scripts in src/qc directory.
3. Run MAS5 normalization using the scripts in src/mas5 directory.
4. Run IQR Gene filter and quantile normalization using scripts in src/filter directory.

Please see the README files in respective directories on how to run these scripts. To prepare annotation from probe elements, helper scripts are available in the src/annotation directory.
