23 <title>Working with PAE Matrices in Jalview</title>
28 <strong>Working with Predicted Alignment Error Matrices in
32 <p>Predicted Alignment Error (PAE) matrices are produced by deep-learning
33 based 3D-structure prediction pipelines such as AlphaFold. They reflect how reliably two parts of a model have been positioned in space, by giving for each residue the likely error (in Angstroms) between the modelled position and the pair of residues' real relative position.</p>
35 Jalview visualises PAE matrices as an alignment annotation track, shaded from dark green to white, as used on the EBI-AlphaFold website (see )
38 <strong>Importing PAE Matrices</strong>
41 Jalview retrieves PAE matrices when importing predicted 3D structures
42 from the EBI-AlphaFold database via <a
43 href="../features/structurechooser.html">Jalview's structure
44 chooser</a> GUI. If you have produced your own models and accompanying
45 PAE matrices using a pipeline such as ColabFold, then you can load
46 them both together via the <a
47 href="../features/structurechooser.html#loadpdbfile">Load PDB
48 File</a> dropdown menu in the 3D structure chooser. in a <a
49 href="../io/paematrixformat.html">supported PAE format</a>.
52 The <a href="../features/clarguments-basic.html">Command Line
53 Interface</a> also provides a options for importing PAE matrices along
54 side models, enabling the automated production of alignment figures
55 annotated with PAE matrices and PLDDT scores.
58 See <a href="../features/paematrices.html">Working with PAE
59 Matrices</a> for information on how they are visualised and analysed in
64 An additional <em>Predicted Alignment Error</em> file can also be
65 provided when importing 3D structure data. Jalview supports import of
66 PAE Matrices provided as <a href="../io/paematrixformat.html">AlphaFold
67 format JSON files</a> - which are also produced by ColabFold. See <a
68 href="paematrices.html">Working with PAE Matrices</a> for details on
69 what Jalview allows you to do with associated PAE matrix data.
