iRefIndex 15.0

January 2018

  • This release of iRefIndex was assembled by Alexander Botzky at the VIB Bioinformatics core (https://www.bits.vib.be/) group in Belgium and Andrei Turinsky at the Hospital for Sick Children in Toronto, Canada with support and guidance from Shoshana Wodak and Ian Donaldson. See https://irefindex.vib.be/
  • This public distribution includes data consolidated using the iRefIndex method for BIND, BioGRID, CORUM, DIP, IntAct, HPRD, MATRIXDB, MPACT, MPPI and MPIDB. MINT is now included in IntAct. New data sources include INTACT COMPLEXES, I2D_IMEX, REACTOME, VIRUSHOST, UNIPROTPP, HPIDB, MOLCON, BHF_UCL and MBINFO.
  • Release 15.0 contains 169,271 new distinct interaction records since release 14.0
  • All of these resources have been integrated from freely available sources. See the sources links below for details.

iRefIndex 14.0

April 2015

  • This public distribution includes data consolidated using the iRefIndex method for BIND, BioGRID, CORUM, DIP, IntAct, HPRD, MATRIXDB, MPACT, MPPI and MPIDB. MINT is now included in IntAct.
  • BIND_TRANSLATION, and INNATEDB are not included due to mapping problems during the build process. These may be returned in a later release. OPHID is permanently removed.
  • An extended version is available only to clients of Donaldson Research and includes new data sources: INTACT COMPLEXES, I2D_IMEX, REACTOME, SPIKE, VIRUSHOST, UNIPROT, HPIDB, MOLCON, BHF_UCL and MBINFO. If you are interested in working with these data in the context of iRefIndex, please contact ian@donaldsonresearch.com.
  • All of these resources have been integrated from freely available sources. See the sources links below for details.
  • Integer identifiers for interactors and interactions are only applicable to the current release - they cannot be used to find an interactor or interaction n a previous release. These integer identifiers include irogida, irogidb, irigid, icrogida, icrogidb and icrigid.
  • The extended version of release 14.0 contains 231,324 new distinct interaction records since release 13.0

iRefIndex 13.0

December 2013

  • MINT records are now distributed by IntAct.
  • All records created by the MINT database are now distributed from the IntAct web-site and FTP site. All MINT interaction records have been assigned an EBI identifier as the record's primary identifier. The original MINT record identifier is preserved as a secondary identifier in the records distributed by IntAct. However, only the EBI identifier is provided in iRefIndex and the source is always listed as IntAct.
  • md5 checksum files are now included in download directories.
  • release 13.0 contains 20460 new distinct interaction records since release 12.0



Known issues that bear repeating based on recent questions

  • Interactions involving small molecules are missing

iRefIndex indexes only those interaction records where ALL of the interactors are proteins. This means that records involving small molecules and proteins will not be indexed. The number of such records is growing mostly due to curation efforts of IntAct and Reactome - the inclusion of interactions involving small molecules will be considered for a future release.

  • Missing genetic interactions

The majority of genetic interactions were removed as of release 10. This was intentional but the change was not noted in this change-log section. The primary source of genetic interactions was the BioGRID database - close to 200 thousand records.

  • More details on known issues

iRefIndex 12.0

June 2013

  • Release 12 corrects the appearance of RefSeq chromosome identifiers that first appeared in release 10 and were used (erroneously) to refer to protein interactors.
  • As of November 30th, 2011, the MINT database produced its last release in PSI-XML format (ftp://mint.bio.uniroma2.it/pub/release/psi/) and now only releases data in PSI-MITAB format (ftp://mint.bio.uniroma2.it/pub/release/mitab26/). The most recent MINT release at the time of writing was from May 20th, 2013. This means that many MINT records are missing from iRefIndex. A new parser will be written to accomodate the PSI-MITAB MINT format for a future release of iRefIndex.


Thanks to Paul Boddie for bug fixes.

iRefIndex 11.0

May 2013

  • Release 11 corrects the appearance of deprecated Entrez Gene Ids found in version 10. This build also includes a module to update iRefWeb.

See the MITAB format description for a complete list of changes related to MITAB output.

Thanks Andrei Turinsky, Lilian Hanna and Paul Boddie for testing and bug fixes.

iRefIndex 10.0

March 2013

  • Release 10 was built using a pipeline rewritten by Paul Boddie to simplify the build process and reduce build time

See the MITAB format description for a complete list of changes related to MITAB output.

Thanks to Aleksandar Stojmirovic, Andrei Turinsky and Thomas Schmitt for early testing.

iRefIndex 9.0

November 2011

  • RIGIDs in previous releases of iRefIndex were incorrectly computed. Although the properties of such RIGIDs were not compromised - distinct RIGIDs should still have referred to distinct interactions - each RIGID made use of substantially less information from its components. RIGIDs in this release should now be computed correctly. (Internal link)
  • Many proteins previously assigned the 4932 taxonomy identifier have been recategorised as having taxonomy identifier 559292. Thus, for convenience, an additional 559292 file is produced alongside the existing (but substantially smaller) 4932 file to hold interactions involving proteins associated with both taxons. (Internal link)
