Downloading Selected Metadata

Metadata files are usually small text files, so you can download them directly to your computer. You do not need to log in before downloading metadata files.

To download selected metadata

1. Filter a study or an assay until you reach a selection of investigation data you are interested in downloading. You may be interested in only the metadata so that you can see how that selection of entities was structured.

2. Click Download Selected Metadata.
   Your browser prompts you to open or save the .zip file.
   

   Info
   It may be useful to rename the .zip file as you save it to include the name of the investigation so that you can identify it more easily. For example, miRNA_metadata.zip.

   
   Follow your browser's instructions to open or save the file.

   Info
   title Archive 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.
