Flag Information |
FINF, FLAG_INFO, NOTE | Profiles of specific subset types and for which a subset effect is found. GEO DataSets are partitioned into subsets that reflect
experimental design. Profiles are flagged as having subset effects if they display differential expression across
experimental variables. CAUTION: The subset effect scoring method is ad hoc, taking into
account group medians, means, deviation inside the groups, penalties and
arbitrary cutoff thresholds. This flag is simply an attempt to give
potentially differentially-regulated genes higher visibility, and is not
intended to provide an absolute determination of significance. | fixed list, check Advanced Search page for list of indexed terms | Find profiles that exhibit subset effects with respect to age or development stage age[Flag Information] OR development stage[Flag Information] |
