Introduction

CyThesaurus is a Cytoscape plugin providing identifier mapping services based on various resources. Currently the plugin support ID mapping resources from delimited text, PGDB file and BioMart web service. This plugin utilized BridgeDb API.

Use Cases

5 related use cases have been identified on Bader Lab ID Mapping page. 2 of them are closely related to this project:

Unification during dataset merging: During a merge operation e.g. of two protein-protein interaction datasets from independently created databases, it is vital to recognize that two protein objects, one from each data source, represent the same protein molecule, even if the protein objects don’t share any database accession numbers. Unification requires knowledge of record type e.g. you cannot reliably use a gene ID to unify proteins (mostly because splice variants exist).
Identifier translation: Some analysis methods require specific translations from one set of identifiers to another. For instance, our 'activity centers' analysis requires translation from protein or gene identifiers in a pathway database to Affymetrix probe set identifiers or other gene expression array platform identifiers.

Supported ID Mapping Resources

File- based

Delimited text file

File format (e.g. http://tinyurl.com/mergesvn/testData/yeast_id_mapping.txt):
- Each column for one ID type
- Each row except the first one represents IDs of different types mapping to each other
- First row contains ID types
- Multiple IDs are allowed to be contained in one cell (One to many mapping, or IDs of the same type maps to each other). Use special character (e.g., ';', '/', etc, or user defined) to separate IDs.

RDB based

PGDB file

Gene database schema: http://www.bridgedb.org/wiki/GeneDatabaseLayout
Gene databases are available at http://bridgedb.org/data/gene_database/

Web service based

BioMart web service

BioMart web service has been utilized to provide ID mapping service in this plugin.

BridgeDb web service

Being developed.

PICR web service

Being developed.

Code Base

Currently the plugin is based on Cytoscape 2.6. Porting to Cytoscape 3.0 is in plan.

ID mapping service for other plugin

An inter-plugin communication module was developed to support CyThesaurus plugin providing ID mapping services to other plugins. It is recommended that other plugins, who need to request ID mapping services from CyThesaurus, include the package cytoscape-plugins-comm (.jar, javadoc, src). The following services are supported.

Test request

Test if the services are available.

  String receiver = "CyThesaurus"; // plugin name when passing messages
  String msgType = Message.MSG_TYPE_TEST; // indicate what this message requests for
  String msgId = receiver + System.currentTimeMillis();
  Message msg = new Message(msgId , pluginName, receiver, msgType , null);
  List<ResponseMessage> response = PluginsCommunicationSupport.sendMessageAndGetResponses(msg);
  if (!response.isempty()) {
      // the ID mapping services are available
  }

ID mapping request

Request to mapping the IDs of source ID types in one attribute to the target ID types and save in the target attribute

  String receiver = "CyThesaurus";
  String msgType = "REQUEST_MAPPING"; // request for ID mapping service
  String msgId = receiver + System.currentTimeMillis();
  Map content = new HashMap();
  content.add("NETWORK_ID", new String[]{"net1", "net2"}); 
  // or content.add("NETWORK_ID", "net1");
  content.add("SOURCE_ATTR", new String[]{"Attr1", "Attr2"});
  // or content.add("SOURCE_ATTR", "ID");
  content.add("SOURCE_ID_TYPE", new String[]{"Type1","Type2"});
  // or content.add("SOURCE_ID_TYPE", "Type1");
  content.add("TARGET_ATTR", "tgtAttr");
  content.add("TARGET_ID_TYPE", "tgtType");
  
  Message msg = new Message(msgId , pluginName, receiver, msgType , content);
  List<ResponseMessage> response = PluginsCommunicationSupport.sendMessageAndGetResponses(msg);
  if (!response.isempty()) {
      Map content = (Map)response.getContent();
      boolean succ = (Boolean) content.get("SUCCESS");
      String report = (String) content.get("REPORT");
      if (succ) {
          // successfully mapped
          // report contains statistics
      } else {
          // failed
          // report contains error message
      }
  } else {
      // the ID mapping services are unavailable
  }

ID mapping dialog request

Request to bring out the ID mapping main dialog

  String receiver = "CyThesaurus";
  String msgType = "MAPPING_DIALOG"; // request for ID mapping main dialog
  String msgId = receiver + System.currentTimeMillis();
  Message msg = new Message(msgId , pluginName, receiver, msgType , null);
  List<ResponseMessage> response = PluginsCommunicationSupport.sendMessageAndGetResponses(msg);
  if (!response.isempty()) {
      Map content = (Map)response.getContent();
      boolean succ = (Boolean) content.get("SUCCESS");
      if (succ) {
          // ID mapping was performed successfully
      } else {
          // ID mapping was not performed or failed
      }
  } else {
      // the ID mapping services are unavailable
  }

ID mapping source config dialog request

Request to bring out the ID mapping source configuration dialog

  String receiver = "CyThesaurus";
  String msgType = "MAPPING_SRC_CONFIG_DIALOG"; // request for ID mapping source configuration dialog
  String msgId = receiver + System.currentTimeMillis();
  Message msg = new Message(msgId , pluginName, receiver, msgType , null);
  List<ResponseMessage> response = PluginsCommunicationSupport.sendMessageAndGetResponses(msg);
  if (!response.isempty()) {
      Map content = (Map)response.getContent();
      boolean succ = (Boolean) content.get("SUCCESS");
      if (succ) {
          // ID mapping sources were configured successfully
      } else {
          // ID mapping sources were not configured or failed
      }
  } else {
      // the ID mapping services are unavailable
  }

ID mapping supported ID types fetching request

Request to fetch the supported source and target ID types

  String receiver = "CyThesaurus";
  String msgType = "REQUEST_SUPPORTED_ID_TYPE"; // request for fetching supported ID types
  String msgId = receiver + System.currentTimeMillis();
  Message msg = new Message(msgId , pluginName, receiver, msgType , null);
  List<ResponseMessage> response = PluginsCommunicationSupport.sendMessageAndGetResponses(msg);
  if (!response.isempty()) {
      Map content = (Map)response.getContent();
      boolean succ = (Boolean) content.get("SUCCESS");
      String report = (String) content.get("REPORT");
      if (succ) {
          // successfully fetched
          // report contains statistics

          String[] supportedSrcIDTypes = (String[]) content.get("SRC_ID_TYPE");
          String[] supportedTgtIDTypes = (String[]) content.get("Tgt_ID_TYPE");
          // do more things here ...
      } else {
          // failed
          // report contains error message
      }
  } else {
      // the ID mapping services are unavailable
  }
