GRAPE: Gene-Ranking Analysis of Pathway Expression
Gene-Ranking Analysis of Pathway Expression (GRAPE) is a tool for
summarizing the consensus behavior of biological pathways in the form of a
template, and for quantifying the extent to which individual samples deviate
from the template. GRAPE templates are based only on the relative rankings
of the genes within the pathway and can be used for classification of tissue
types or disease subtypes. GRAPE can be used to represent gene-expression
samples as vectors of pathway scores, where each pathway score indicates the
departure from a given collection of reference samples. The resulting pathway-
space representation can be used as the feature set for various applications,
including survival analysis and drug-response prediction.
