1. AlphaFold2
1-1. MSA Data
Format: Pickle format
Contents: Multiple Sequence Alignment (MSA) data.
1-2. MSA Coverage
Information on the coverage of sequences in the MSA.
1-3. Predicted Alignment Error
Prediction of errors in the alignment.
1-4. Predicted Contacts
Predicted residue-residue contacts, showing which residues are predicted to be close in the 3D structure.
1-5. Predicted Distogram
A distance histogram, indicating predicted distances between pairs of residues.
1-6. Predicted Local Distance Difference Test (LDDT)
A quality measure of the predicted structure, evaluating the local distance between atoms in the predicted structure and a reference structure.
1-7. Structures (Rank 1 to Rank 5)
Raw Data: Structures corresponding to the top 5 prediction ranks.
PAE Data: Prediction Accuracy Estimation (PAE) data in JSON format.
Unrelaxed Structure: The unrelaxed version of the predicted structure in PDB format, which is the initial structure before any energy minimization or relaxation steps.
