Hallucination framework (F_vHallucinator) for generating antibody F_v libraries conditioned on structure. F_vHallucinator is adapted from trDesign (26) for antibody design. An ensemble of pretrained DeepAb (28) models is used to predict the structure of a designed sequence. The error/loss between predicted structure and target structure is minimized iteratively to arrive at a sequence that folds into the target structure as predicted by DeepAb.
