The official string-db.org PSICQUIC implementation.
The STRING-DB PSICQUIC API is not equivalent/compatible with the STRING-DB’s API :
- it provides just a subset of all data available (only the core species – 417 out of 1133 in v9.1), and only interactions with score > 400 are indexed)
- each STRING-DB evidence channel is reported as a separate interaction (homology excluded, all transferred combined into one)
- get JDK 1.7 (or newer) and Maven 3
- run
mvn generate-sourcesand add target/generated/java as a source folder - edit
docs/psicquic.properties.templateand put under/opt/stringdb/v10.0/psicquic.properties, but make sure it’s in sync withpsicquic-indexing-spring-test.xml - edit
docs/jdbc-v1.0.properties.templateand save at/opt/stringdb/jdbc-v1.0.properties
As of v10 we will not be running the REST service but only provide mitab files for download. To generate them run:
MAVEN_OPTS=" -Xmx16g " mvn -PexportMitab install
Run: MAVEN_OPTS=" -Xmx2559m " mvn -PcreateIndexWithSolrRunning install
Run: mvn -DskipTests=true -Pstart-jetty-solr package jetty:run
This will start jetty locally which can be accessed at
http://localhost:9090/psicquic/webservices/current/search/query/species:9606?firstResult=0&maxResults=10
This section explains how is string-db’s database data converted to PsiMiTab format for indexing.
The reference is MITAB27Format .
| MiTab Column | Header |
|---|---|
| 1&2. unique identifier | external_id and uniprotId |
| 3&4. alternative identifiers | uniprot & refseq |
| 5&6. aliases | preferred protein name |
| 7. Interaction detection methods |
|
| 8. First author | – |
| 9. publication id | – |
| 10&11. NCBI tax ids | species id(name) |
| 12. Interaction types |
|
| 13. source db | for experimental & database channels, map {protein_id → collection_id} using evidence.sets_items and from evidence.sets, then map {collection_id → miterm} as following:
for all other channels: psi-mi:“MI:1014”(string) |
| 14. interaction ID | we don’t have them |
| 15. score | For non-transferred channels (except homology) its as reported in the database. All transferred channels (except homology) – are combined into one score. See StringDbScores#getTransferredScore for details. |
| 16. Complex expansion | – |
| 17 & 18. Biological roles | ID: MI:0499 (unspecified role), go to the source DB to find out |
| 19&20. Experimental roles | ID: MI:0499 (unspecified role), go to the source DB to find out |
| 21&22. Interactor types | ID: MI:0326 Name: protein |
| 23&24. Xref for interactors | – |
| 25. Xref for the interaction | – |
| 26&27. Annotations for interactors | – |
| 28&29 Annotations for the interaction | – |
| 30. Host id | – |
| 31. Creation date | – |
| 32. Update date | – |
| 33 & 34 Interactors checksums | ROGID |
| 35. Interaction checksum | – |
| 36. Negative interaction | – |
| 37 & 38. Features | – |
| 39 & 40. Stoichiometry | – |
| 41 & 42. Participant identification method | – |
