TCGA GRCh38 metadata
ABOUT METADATA FOR DATASETS > TCGA GRCh38 metadata
On this page:
Overview
Metadata is data that describes other data. On this page, we've detailed TCGA metadata that are available for viewing and filtering TCGA data in the Data Browser and the Datasets API. TCGA metadata on the CGC consists of properties which describe the entities of the TCGA dataset.
Entities are particular resources with UUIDs, such as files, cases, samples, and cell lines.
Properties can either describe an entity or relate that entity to another entity. For instance, properties include an entity's vital status, gender, data format, or experimental strategy.

File
The file entity refers to the files in TCGA produced by aliquot analyses. Members of the file entity can be identified by a Universally Unique Identifier (UUID). Find the properties of the file entity below.
| Property | Description |
|---|---|
| Submitter ID | Usually a human-readable identifier, such as a number or a string that may contain metadata information. In some instances, this can also be a UUID. |
| Data category | The classification of data used in (or produced by) the analysis, based on its form and content. See NCI Thesaurus Code: C42645. |
| Data type | A further, more specific classification of the data category, based on the information that it contains. |
| Data format | The type of format that determines data content. |
| Experimental strategy | The method or protocol used to perform the laboratory analysis. See NCI Thesaurus Code: C43622. |
| File size | The size of a file measured in bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and larger values. |
| Access level | A Boolean value indicating Controlled Data or Open Data. Controlled Data is data from public datasets that has limitations on use and requires approval by dbGaP. Open Data is data from public datasets that doesn't have limitations on its use. |
| Platform | The version (for instance, manufacturer or model) of the technology that was used for sequencing or assaying. See NCI Thesaurus Code: C45378. |
| Genome build | The reference genome or assembly (such as HG19/GRCh37 or GRCh38) to which the nucleotide sequence of a case/subject/sample can be aligned. |
| Genome name | The reference genome or assembly that also contains decoy viral sequence to which the nucleotide sequence of a case/subject/sample can be aligned. |
| GDC file UUID | The unique identifier for a file, such as a UUID. |
Analysis
