- SDRF.
- Controlled vocabularies should be used in IDF and SDRF files. The commonly used vocabularies can be found in MGED Ontology (MO) or the NCI Thesaurus. Each TERM SOURCE REF should have an entry in the IDF file. If term source is unknown, use "caArray" in the TERM SOURCE REF column. See Term Source REF.
- All column types are not mandatory in the SDRF. caArray can auto-generate missing biomaterials and associate protocols intelligently.
For a detailed list of recognized fields and validation rules for IDF and SDRF files, refer to Appendix A in the User's Guide.
MAGE-TAB Files: Upload and Import
See Importing MAGE-TAB Data in the caArray User's Guide for more information about all points noted in this section.
- MAGE-TAB Files must be imported into experiments. That is, an experiment needs to be created before MAGE-TAB files are imported.
- Although only one IDF is allowed per import session, multiple IDF files are allowed per experiment.
- IDF, SDRF(s), data file(s) referenced in SDRF files must be validated and imported together.
- Data files that are not referred to by SDRF files can also be imported into the same experiment, but they must be uploaded, validated and imported in a separate session from IDF/DSRF files.
- MAGE-TAB ADF and Data Matrix files can be uploaded, but caArray does not parse these files. the exception is copy number data matrix files, which caArray does parse. See About File Types in caArray.
SDRF File Has Higher Priority
Annotations can be configured via the Annotations tab in caArray or via an SDRF file (Annotations Tab vs. MAGE-TAB Annotation Files in caArray). The designation in the SDRF is authoritative. For example: The tissue site for one sample is set to be "Lung" from the annotation interface, but it is set to be "Brain" in the SDRF file. Upon data upload, the tissue site will be shown as "Brain", since SDRF file has higher priority than "Annotation" interface. See SDRF Decides Raw versus Derived Data File.
