| Description |
Specifies how samples are combined to form composite sample groups.
Each sample group has an ID (column: ID), a list of members or child groups
(column: Members) and a type (column: Type). Members can be composite groups
as well and they do not have to present in the same SampleGroupTable. The
type specifies how numeric values for a composite group can be obtained from
child groups. Standard values for type are sample, median, mean and ratio.
If the type is ratio, there must be exactly two members and their order is
significant: ratio(A, B) = A/B. If the sample group represents an atomic
sample with one member, type should be sample. Type can be any other value
as well: individual components define which types they understand. Type can
be NA if the information is not relevant. In addition to mandatory columns,
an optional column Description may be present. It contains free-format
human-readable text. |
