I am trying to model a tetramer. The number of residues in the target protein are 141 each in 2 subunits and 146 each in the other two. The target is single, also a tetramer with the same number of amino acids in the four subunits. Following is the format of the alignment file: C; alignment in the PIR format

>P1;----- structureX:-----:1:A:146:D:name:source:: ------------------------------------------------------------------------- ---------------------------------------------/ ------------------------------------------------------------------------- ---------------------------------------------/ ------------------------------------------------------------------------- ---------------------------------------------/ ------------------------------------------------------------------------- ---------------------------------------------*

>P1;----- sequence:-----:1:A:146:D:name:source:: ------------------------------------------------------------------------- ---------------------------------------------/ ------------------------------------------------------------------------- ---------------------------------------------/ ------------------------------------------------------------------------- ---------------------------------------------/ ------------------------------------------------------------------------- ---------------------------------------------*

Please make sure that the above format is correct. Moreover the total number of residues amounts to above 1000 which is more than the specified limit. Please suggest the solution. Thanks
