Why are there different correlation filters for inter and intra-omics?

The correlations between 'omics features within the same data is usually categorically higher than correlations between 'omics features of different omics types, likely due to systematic differences in platforms and methods used to collect the data.

Because of this, using a single threshold to prioritize which edges to display will result in the vast majority of edges being between features of the same 'omics type. OmicsAnalyst has two thresholds to allow users to relax the threshold for inter-omics connections to create more balanced networks.
