Description Details References
The spqn package implements spatial quantile normalization (SpQN). This method was developed to remove a mean-correlation relationship in correlation matrices built from gene expression data. It can serve as pre-processing step prior to a co-expression analysis.
See references for details on spatial quantile normalization.
The main function is normalize_correlation
. We include a number
of plotting functions for examining the mean-correlation relationship,
see the vignette for examples.
