I mapped a dataset of observational / survey data to standard concepts as well as several custom concepts ( with IDs > 2B) due to missing coverage with standard concepts.
When I look up the dataset in a local ATLAS instance, in the Data Sources tab, all standard and custom records show up in the tables / treemaps, and the total # of observational entities matches the number in the source dataset.
However, when I search for a concept ID in the Search tab, only the standard concepts can be located, whereas custom concepts when searched produce a “NO RESULTS FOUND FOR …” message. This in turn impedes the creation of concept sets with custom concepts for cohort generation etc.
Does anyone have an idea how to resolve this (i.e. ATLAS recognizing custom concepts in some context but not others)?
