I had used the old DIME for submitting samples and test results, how do I find those samples and results?
The old DIME Sample ID was in the format of yyyy-mm-dd-hh-mm-dddd, where yyyy is the year of the sample taken date, mm is the month, dd is the day, hh is the hour, mm is the minute, and dddd is the random 4 digits provided by the system. In the current version of the system, DIME Sample ID are now in the format of yyy-mm-dd-hhmmdddd. The updated system provides a few ways to find a sample.
