Generating Sequence Logo from single RNA-protein complex

NucleicNet can readily generate sequence logo diagrams using our prediction result when base locations are ascertained by a single RNA-protein complex. Please upload a protein structure model without any RNA below.
To allow a uniform processing of PDB files, users are recommended to check validity of their input files by observing criteria specified on

For small size protein (e.g. PDBID: 2adc with < 300 residues), full run should take less than 5 minutes.
For large size protein (e.g. PDBID: 4f3t with > 800 residues), full run could take more than 10 minutes.
