Builds gene regulatory network for NicheNet using OmniPathSource:
Retrieves network prior knowledge from OmniPath and provides it in
a format suitable for NicheNet.
This method never downloads the `ligrecextra` dataset because the
ligand-receptor interactions are supposed to come from
Lower threshold for curation effort
A network data frame (tibble) with gene regulatory interactions suitable for use with NicheNet.
# use interactions up to confidence level "C" from DoRothEA: op_gr_network <- nichenet_gr_network_omnipath( dorothea_levels = c('A', 'B', 'C') )
