RiceNCexp employs 491 RNA-seq datasets, which are used to calculate the expression of lncRNAs, PHAS genes and protein-coding genes and 274 sRNA-seq datasets, which are used to calculate the expression of miRNAs and phasiRNAs. Moreover, 116 pairs of datasets, with both RNA-seq and sRNA-seq from the same experiments, are used for co-expression analysis by Pearson Correlation Coefficient (PCC).
