Option 1
(Upload your sequence alignment and template structure file)

Sequence alignment (FASTA format)

Please make sure that the template sequence is the upper one in the alignment. Example

Template structure (PDB format)

Please make sure that this is the structure file of the template sequence in the alignment.
Please make sure that the template structure is fitted in the approximate position of your target protein in the density map.

Number of models to build

Please make sure that this value is an integer and greater than zero.
If you type in a float number CHOYCE will use its integer value.

Option 2
(Upload your target sequence and template structure file; we will align them)

Target sequence (FASTA format)

Template structure (PDB format)

Please make sure that the template structure is fitted in the approximate position of your target protein in the density map.

Number of alignments to build

Please make sure that this value is an integer and greater-than-or-equal THREE.
If you type in a float number CHOYCE will use its integer value.
CHOYCE WILL BUILD 10 MODELS PER ALIGNMENT.
