Many functions in dccvalidator use reticulate and the Synapse Python client. See the reticulate documentation for information on how to set R to use a specific version of Python if you don’t want to use the default Python installation on your machine. Whichever Python installation you choose should have synapseclient installed.

Because dccvalidator uses reticulate, it is not compatible with the synapser package..

Check data

dccvalidator provides functions for checking the following common data quality issues:

Data submission validation

This package contains a Shiny app to validate manifests and metadata for AMP-AD studies. It uses the dccvalidator package to check for common data quality issues and gives realtime feedback to the data contributor on errors that need to be fixed. The reporting UI is heavily inspired by the MetaDIG project’s metadata quality reports.

The application also allows users to submit documentation of their study, a description of the methods used, etc.

See the customizing dccvalidator vignette for information on how to spin up a customized version of the application
