**Input parameters**:
**Select a method for input normalization**:
Normalization is used to remove unwanted variation and normalize between arrays. You can choose from five different normalization methods:
1. Functional normalization
2. Noob normalization
3. SWAN normalization
4. Quantile normalization
5. Illumina Genome Studio normalization
Additionaly, you can skip the normalization step by selecting *No normalization - use raw values*.
**Detection p-value threshold for failed probe identification**:
Every probe on the array has a detection p-value assigned, which indicates confidence of the scanner that the detection was correct. A probe will be marked as *failed* in a sample if its detection p-value is higher that the given value.
Together with the
**Failed sample threshold**:
You can subsequently exclude probes that have a certain proportion of failed marks across all samples.
**Q-value cutoff for multiple testing**:
Multiple testing is done automatically by ADMIRE and corrects the test statistic for multiple performed tests. If a certain region remains with a Q-value or FDR below the given value, it will be retained for subsequent analysis, like the gene set enrichment analysis or visualizations.
**Number of additional plots for n best regions**:
The number given here will determine how many visualizations are plotted for significant regions. Importantly, if the number of samples is higher than 100, a heatmap is created. Otherwise, non-proportional bubble plots are plotted.
**Select genomic regions to test**:
Regions selected here will be overlapped with methylation probes and significant different methylated regions will be reported.
By uploading bed files to the work space (right panel), users can give custom regions by adding them to the **custom genomic regions** list.
**Choose gene sets**:
If a gene set is given (either by selecting pre-defined gene sets or uploading a custom gene set), a gene set enrichment analysis is performed by taking all significantly different methylathed regions that are annotated with a gene name and testing them for enrichment in a gene set.
Regions with annotated gene names are *Promoter Regions (2kB)* and *Exons*.

**Output files**:
**compressed output**:
The complete output of admire compressed into a tar.gz file. This file is intended for download and extraction on your local hard drive. When extracted, it contains
* Files in the excel subdirectory: This subdirectory contains csv files for each combination of sample group comparison (e.g. case-vs-control) and genomic region (e.g. promoters), with information about the genomic feature, its genomic location as well as p- and q-values of the sample groups. In addition to a file with all regions passing the q-value threshold, a file containing all regions is also present.
* Files in the visualization subdirectory: This subdirectory contains files for visualization with IGV. General files, like the genomic location of all Illumina probes, as well as the genomics regions used during analysis, are located in the `annotation-tracks` subfolder. Data specific files are located in the `data-tracks` folder. Here, you can find information per sample-group comparison (e.g. case-vs-control), information on significantly altered probe methylation (`control-case.igv`), as well as significantly altered genomic regions in [BED format]( Additionally, publication-ready images are stored in region-specific subdirectories.
**Quality control report**
A PDF file that can be used to check the per sample quality. This file is generated by the R package *minfi*'s quality control routines.
**admire output**:
This file gives information on the admire run. In case of errors, you can find them here.

**Use the example data sets provided by ADMIRE**
Browse to the shared data library_ to load an example sample definition file into galaxy. The sample definition file contains file paths for the IDAT files from the GEO experiment E-GEOD-62727 that is stored on our server. Next, choose the ADMIRE tool and use the experiment_design.txt as input into the pipeline. Choose some genomic regions (e.g. 5kbp and 10kbp tiling regions to reproduce our findings from the paper) and hit Execute to see the tool in action.
**Step by step instructions**
Graphical step by step instructions on how to use the example data sets can be found at
