Description

DF_ICcenters checks the sites database for common errors and inconsistencies, reporting both errors (problems which will definitely impact the ability to communicate with the sites via DFdiscover) and warnings (problems which may impact communication).

DF_ICcenters should be used to detect errors after DFcenters has been defined but before study setup testing is complete. Ideally, DF_ICcenters will list no errors or warnings at the time data collection begins and thereafter.

If DFcenters is defined using the Sites view dialog in DFsetup, there are already some syntax checks in place that will detect inconsistencies such as out of range values. DF_ICcenters applies additional checks to the sites database that are not applied (or not known) in the Sites view editor. All site definitions that fail these checks are listed as the report output. Each failed check is categorized as either ERROR or WARNING. The ERROR categorization indicates a site definition that will definitely lead to problems in communication. A WARNING categorization indicates a site definition that may or may not lead to problems in communication, and hence should be investigated further.

When inconsistencies are detected by DF_ICcenters, each problem is identified with the beginning of the offending record in DFcenters followed by the ERROR or WARNING tag and a brief description of the problem. If multiple problems are detected within the same record, the offending record is only displayed once followed by a list of ERROR and/or WARNING problems. The exception to this is if problems are detected with the Subject ID entry. DF_ICcenters checks the Subject ID field separately from other fields in DFcenters. Hence it is possible for the offending record to appear more than once in the output if it has problems with both the Subject ID and other fields.

DF_ICcenters can be executed from the DFexplore Reports View, by using Verify available in the Sites view dialog in DFsetup, or by using File > Verify All also from DFsetup.
