The screenshots of the isoform interaction and module search function in the IIIDB. (A) Users can upload their own gene expression data for III prediction. (B) IIIDB shows top 100 IIIs and uses these interactions to construct an III network. Users can download complete prediction result as a file. (C) In interaction search function, users can input a gene symbol or gene ID to search associated IIIs and isoform modules. The interaction search section provides interface on searching high-confidence (score > 2.575) or low-confidence (score > 1.692) prediction. The resulting III table for interaction search shows full evidence values including Pearson correlations for 19 RNA-seq datasets and domain interaction score. (D) The resulting page for module search includes the user friendly network graph and pathway/GO enrichment analysis result.
