• Specify template with alignment: This option allows you (usually advanced users) to specify both template structure and the target-template alignment. You can use either 3D Format or FASTA Format.

    The 3D Format is similar as the standard PDB format but two more columns are added from the template sequences, e.g.

    ATOM   2001  CA  MET     1      41.116 -30.727   6.866  129 THR
ATOM   2002  CA  ALA     2      39.261 -27.408   6.496  130 ARG
ATOM   2003  CA  ALA     3      35.665 -27.370   7.726  131 THR
ATOM   2004  CA  ARG     4      32.662 -25.111   7.172  132 ARG
ATOM   2005  CA  GLY     5      29.121 -25.194   8.602  133 ARG

Column 1 -30: Atom & Residue records of query sequence.
Column 31-54: Coordinates of atoms in query copied from corresponding atoms in template.
Column 55-59: Corresponding residue number in template based on alignment
Column 60-64: Corresponding residue name in template
    The FASTA Format is similar as the standard FASTA format except that the 3D structure is attached after the sequence alignemnts. e.g. 
    >TARGET

    Note:
    (a) To avoid the possible error in reproducing template structure and alignments, rather than specifying PDB ID, the users who use FASTA format must attach the original PDB structure of the template in the FASTA file, see the example.
    (b) The query name specified in the FASTA alignment (in the above example as "TARGET") should be the same as the name specified in ID form on the submission page. If you leave the ID form blank, the description line of query in the FASTA alignment should be specified as ">your_protein".
