Data Submissions to the DCC
GCC data for the TCGA project is also known as Array-Based Data.
GCC Results Files
For GCCs, each TCGA result file has a Data Type and corresponding Data Level. A TCGA result file is any file that is listed in the SDRF file under column header ending in "File" (such as "Derived Array Data Matrix File").
To determine the Data Level of a file, look under its corresponding "Comment [TCGA Data Level]" column. Similarly, to determine the Data Type of a file, look under the "Comment [TCGA Data Type]" column of the SDRF file. If you follow a row of data from its Extract Name and onwards, you can see how a data file progresses through the Data Levels as protocols (or procedures) are applied.
The figure below is an excerpt of an SDRF file. In this section of the file, the data files (under "Derived Array Data Matrix File") are text (.txt) files, the Data Level (under "Comment [TCGA Data Level]") is Level 2 and the data type (under "Comment [TCGA Data Type]") is DNA-Methylation.
