Access detailed metadata

In the side panel, you can find an overview of the metadata that is available for this dataset. For example:

1. The data descriptor is a pdf text file with detailed information about the dataset, including the methods, technical validation, usage notes and data organisation.
2. Detailed subject metadata can be found in a separate tab (see below).

In this dataset, a number of subjects were used with a C57BL/6J (wildtype) genotype. These were 4-9 months old (adult mice) with a weight between 38 - 47 gram. They were tested three times under aneasthesia, which is captured by the "studied states" of the subject. Additional details regarding the tests is stored under additional remarks (currently not visible in the image).

Access and download data

To get an overview of the data files in the dataset and to be able to download them, go to the "Get data" tab in the side panel. The full dataset can be downloaded, or you can choose a single file to download. Files can be filtered based on the content type of the file (i.e. file format and software that can open it). Once you found a file that you are interested in, you can click on it. On the right side of the file list, you can press the download file button to download the individual file. You may also find additional information about the content type of the file and which software can open such a file type.
