Download NTP Study Data
NTP seeks to engage researchers and members of the public who may be interested in accessing study data. For those interested in a detailed look at studies, retrieving current study data is as simple as the download of a few files.
Summary data on all NTP chemicals can be downloaded in a single file. If you would like more detailed data, you can download an individual study type. The following study types are available for detailed data downloads:
- CHO cell cytogenesis
- Mouse lymphoma
- Rodent cytogenetics
NTP will update the data on a quarterly basis.
Format of NTP Data Downloads
NTP uses XML to create these data files. XML is a free, open standard computer language with a set of rules that encodes documents in machine readable format. The XML files contain the data; schema files show how that data is organized and formatted. For additional information, see the World Wide Web Consortium's XML Technology section.
Although you can open and read XML and schema files in a text editor, it is unwieldy to view the downloaded files this way. Most files will be too large to open in Excel. Typically, bioinformaticians or computer programmers would use these files to bring NTP data into your applications or databases.
NTP Test Article and Study Data
Formatting common to all XML files is described in the Custom Type Schema (22 KB - Sept. 6, 2013).
