The geWorkbench platform employs a component repository infrastructure to manage a large collection of pluggable components that can be used to customize the application's graphical user interface. This (ever growing) list of plug-in components covers a wide range of fucntionality for a number of different genomic data modalities:

Normalizers
| Plugin |
Description |
Compatibility
|

TBD
|
| Marker-Based Centering |
Subtracts the mean (median) measurement of a marker profile from every measurement in the profile. |
TBD
|
| Mean-Variance Normalizer |
For every marker profile, the mean measurement of the entire profile is subtracted from each measurement in the profile and the resulting value is divided by the standard deviation.
|
TBD
|
| Missing Value Calculation |
Replaces every missing value with either the mean value of that marker across all microarrays or with the mean measurement of all markers in the microarray.
|
TBD
|
| Threshold Normalizer |
All data points whose value is less than (or greater than) a user-specified minimum (maximum) value are raised (reduced) to that minimum (maximum) value. |
TBD
|
| Quantile |
Expression measurements in each microarray is adjusted to reflect the same expression value distribution for all microarrays. |
TBD
|
| Housekeeping |
Normalization based on the average expression of all markers corresponding to user selected housekeeping genes. |

?
|
| Self Organizing Map (SOM) |
An algorithm to perform clustering of real vectors defined on an instance space of dimensionality. |
?
|
| T Test |
The t-test determines if for each marker there is a significant difference between two groups.The T-test analysis implementation is based on code from the Multi Experiment Viewer (MEV) platform (http://www.tm4.org/mev.html). |
