Original hybridization signal data were log transformed and median centered prior clustering (hierarchical cluster for genes, correlation uncentered with average linkage).
Also, the performance of enrichment analysis is profoundly dependent on prior clustering result, which varies considerably according to the cluster methods and parameter settings.
Regression trees do not rely on a prior clustering of genes into groups, and provide rules that best describe the observed distribution of fold changes.
Female sex was associated with case status among patients in the BBG cluster; however, sex differences have not been reported for prior clusters of Fusarium endophthalmitis patients (20, 21 ).
However, we intended to develop a simple, but effective method for testing the significant occurrence of various motifs and modules at the same time in unprocessed lists of genes without prior clustering.
Results were indexed with the aid of a prior-clustering and annotation exercise.
Finally, Adaptive Clustering incorporates the previously generated clustering atlas as a prior, to cluster the fibers of a new subject automatically.
The three sets of gene clusters were generated consecutively with each prior gene cluster serving as the seed for the next gene cluster (fig. 2 A).
All profiles selected for clustering were smoothed prior to clustering using Gaussian convolution with window size of 7 bins.
