The multiple protein alignment

Upload a file with a multiple protein alignment in fasta format. File size must not exceed 50 MB. File extention must be "fasta" or "fasta_aln". E.g.: filename.fasta_aln.
The representative protein structure

Upload a file with protein structure in the PDB format. File size must not exceed 10 MB. File extention must be "pdb". E.g.: filename.pdb.
Enter a chain ID (e.g., 'A' to select chain A or 'first' to select the first chain in the uploaded file)
Enter a positive integer (e.g., '10' to select the 10-th protein in the alignment to match the protein structure, or 'auto' to select the best match automatically)
Select the MI-based score measure of residue correlation
The MIc / Zc statistics
The MIp / Zp statistics
Select the Mutial Information-based score measure of residue correlation
