true_ca_poses: a list of tensors, corresponding to the c-alpha positions of the ground truth structure. e.g. If there are 5 chains, this list will have a length of 5
anchor_gt_idx (Tensor): a tensor with one integer in it. The index of selected ground truth anchor.
anchor_gt_residue:a list of residue indexes that belongs to the selected ground truth anchor
anchor_gt_residue:a 1D vector tensor of residue indexes that belongs to the selected ground truth anchor
true_ca_masks: list of masks from ground truth chains e.g. it will be length=5 if there are 5 chains in ground truth structure
pred_ca_mask: A boolean tensor corresponds to the mask to mask the predicted features
asym_mask: A boolean tensor that mask out other elements in a tensor if they do not belong to a this asym_id
