Provide protein structures (no more than 20 structures) using one of the following methods (help):

Leave blank or use one dot(.) for un-specified chain Id, then the 1st chain will be used; To specify a space chain Id, please use two dots(..); Any space Chain Id will be renamed with a new unique alphanumeric Chain Id.

Enter a list of PDB or SCOP codes and constrains in the input table (leave unused entries blank, example):
Index PDB Chain Segments Reference Other Chains Upload Your Own Structure File if no PDB/SCOP code
Add 1, 5 or 10 protein structures.

Copy and paste a list of PDB codes and constrains here (example):

Provide PDB codes separated by spaces:

Currently unavailable
Upload a tar/zip file for a list of PDB structure files (one and only one chain for each PDB file, otherwise the first chain is used)

Enter a list of SCOP domain codes separated by space:
