    titleArchive File Contents

    The archive file is in compressed format. When you download it, it may be a single compressed folder or .zip file. When you open it, you see at minimum three text files at the root of the folder or file. An example of these follow. 

       a_10290.txt

       i_10290.txt

       s_10290.txt

    The text files describe the investigation, study or studies, and assay or assays. In this example, 10290 represents the file identifier but in practice, each file identifier may be named differently, even in the same investigation. Only the a, i, or s prefix is required. If you download full data or selected data, the archive may also contain other files or folders as appropriate for the investigation; for example, images. If you download metadata, the archive only includes the a, i, and s files.
