**What it does**

Analyze TCGA illumina 450k array data hosted at the GDAC Broadinstitute firehose.
http://gdac.broadinstitute.org/runs/stddata__latest/

**Input**:

Currently, an example of a file that this function reads is here:

<http://gdac.broadinstitute.org/runs/stddata__2014_10_17/data/UCEC/20141017/gdac.broadinstitute.org_UCEC.Merge_methylation__humanmethylation450__jhu_usc_edu__Level_3__within_bioassay_data_set_function__data.Level_3.2014101700.0.0.tar.gz>


NOTE: It is an archive of size 8.1Gb

1. Upload the file into galaxy.

2. Run the "Minfi Analysis pipeline for TCGA data" tool on the resultant tar file in your history.

3. This will generate two results, Differentially methylated positions and Differentially methylated regions.

**Output**:

1. Differentially methylated positions

2. Differentially methylated regions.
