2 Structure quantizer

Structure quantizer

from prosst.structure.quantizer import PdbQuantizer
processor = PdbQuantizer(structure_vocab_size=2048) # can be 20, 128, 512, 1024, 2048, 4096
result = processor("example_data/p1.pdb", return_residue_seq=False)

Output:

[407, 998, 1841, 1421, 653, 450, 117, 822, ...]
