Error in rowMeans(GCMat[key_df$gene.1, ]) :

[cdkodira1]

I ran this code with your example files: netList <- RunMLnet(GCMat, BarCluFile, RecClu, LigClu, pval, logfc, LigRecLib, TFTarLib, RecTFLib)

I got this error :

Error in rowMeans(GCMat[key_df$gene.1, ]) : 'x' must be an array of at least two dimensions
