the column range that specifies the causes (miRNAs), e.g. 1:35
the column range that specifies the effects (mRNAs), e.g. 36:2000
the putative target, e.g. "TargetScan.csv". If targetbinding is not specified, only expression data is used.
If targetbinding is specified, the prediction results using expression data with be intersected with the interactions in the target binding file.
A matrix that includes the Kendall correlation coefficients. Columns are miRNAs, rows are mRNAs.
