# Supplementary data files Addtional information about the files in the minimum data deposition can be included in our supplementary data files. The [ASSAY\_PARAM](/chembl-data-deposition-guide/file-structure/supplementary-data-files/assay_param.tsv-adding-additional-assay-information..md) file can be used to include details about the setup of the ASSAY, for example the concentration of compound used, the pH of the buffer, the instrument used for data collection or the timepoints of the experiment. The [ACTIVITY\_PROPERTIES](/chembl-data-deposition-guide/file-structure/supplementary-data-files/activity_properties.tsv-adding-context-to-experimental-results.md) file provides a mechanism for attaching additional information to activity files. This is important for assays which generate values of a single result type, in which the values quoted must be qualified with another parameter that has been measured or set in the ACTIVITY file. An INFO file can be included in a deposition but will not be loaded to the database. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://chembl.gitbook.io/chembl-data-deposition-guide/file-structure/supplementary-data-files.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
