Generally, when you search for aliquots, you are interested only in a subset that should be displayed in the query results and not all aliquots under a specimen. Using the 'Aliquot Sequence' filter, limiting the number of aliquots displayed per parent specimen in the query results is possible.
It is a dynamic virtual counter. It generates the sequence for the aliquots under a parent specimen for the query, starting from 1.
For example, a user wants to view 1 aliquot parent specimen. A filter can be applied in the query as "Specimen >> Specimen Statistics >> Aliquot Sequence Equals 1"
A system job, 'Scheduler to refresh specimen additional details,' is scheduled to run every night. This allows the updating of the aliquot sequence. More information on jobs: System Jobs
