Plug-in and extensions download

The latest stable BASE can be downloaded from the ​BASE 2 development site. The latest BASE 1 release is available from ​BASE 1.2.x download area and the latest ​BASE 1.2 plug-in development kit may be needed for some of the BASE 1 plug-ins.

BASE 2

BASE 2 come pre-installed with a set of core plug-ins, information about these is available elsewhere (​list of BASE 2 core plug-ins).

Plug-ins

Plug-ins available for download are listed in the table below.

Name	Type	BASE version	Maintainer	Comment
AffyArrayDesignBatchImporter	Import	2.2	None	Imports batches of Affymetrix array design.
AnnotationTypeCvImporter	Import	2.0	None	Import annotation type and controlled vocabularies from a simple flat file.
BatchDataImporter	Import	2.2	Micha Bayer	Imports batches of data files into BASE, creating a single RawbioAssay for each file.
GCRMA	Normalization	2.0	Patrick Ahles	Normalization of Affymetrix data
Illumina plug-ins package	Add array platform	2.12	Lund team	A package of plug-ins for working with Illumina Sentrix and Illumina SNP arrays.
Tab2MageExporter	Export	2.14.1	None	Exports an experiment meta-data in the tab2mage specification.
Tab2MageImporter	Import	2.2	None	Imports raw data files and an experiment meta-data in the tab2mage specification.

• Type is categorization of plug-ins. Plug-ins of 'Add array platform' type will extend a BASE installation to support further array platforms. A base set of plug-ins are provided such as import of raw data and normalization.
  
• BASE version refers to the earliest BASE version usable with the current release of the plug-in.
  
• Maintainer shows the current maintainer of a plug-in. Plug-ins that have no maintainer are indicated with 'None'. Unmaintained plug-ins are included in the table until they are reported to be broken. If you want to volunteer to maintain a plug-in then make yourself known through the ​BASE developer mailing list.

Normalization

Affymetrix plug-in for BASE: Affymetrix normalization with RMAExpress or Plier (​download latest ​MD5). The Plier algorithm in this plug-in is superseded by the ​APT plug-in. Works with BASE 2.0 and later
​APT: Affymetrix Power Tools execution plug-in. Currently apt-probeset-summarize and apt-probeset-geneotype from APT is acccessible through this plug-in. Works with BASE 2.4 and later
Normalization package: A package with different kinds of normalization plug-ins. Works with BASE 2.7 and later

Transformation

WeNNI: Missing value imputation. Not released yet

Un-categorized

BAFsegmentation: Segments B allele frequencies from SNP arrays to identify regions of allelic imbalance. Not released yet

Web client extensions

An extension mechanism was introduced in the BASE 2.7 web client. Extensions are mainly used for adding functionality the GUI, such as extra menus and buttons.

FTP Server

An extension that adds an FTP server to BASE, making it possible to upload/download files to/from BASE using regular FTP client software. Works with BASE 2.10 and later.

MEV Launcher

Integrates BASE with ​TIGR MultiExperiment Viewer (MEV). Works with BASE 2.7 and later, but BASE 2.13 is recommended.

Example code

Plug-ins

Example plug-ins for BASE2: A package with example plug-ins intended for the developer. Works with BASE 2.6 and later

Web services

Web services examples for BASE 2: A package with a Java client application that uses web services to get information from a BASE 2 server. Works with BASE 2.6 and later

Extensions

Example extensions for the BASE web client: A package with several "Hello world" examples of extensions to the web client. Works with BASE 2.7 and later, but BASE 2.13 is recommended.

BASE 1.2 plug-ins

Plug-ins created for BASE 1.2 can be made to work in BASE 2 using the Base1PluginExecuter plug-in.
