It is not clear what this means.

<p>I have downloaded a predicted structure from AlphaFold as a pdb file (<a href="https://alphafold.com/entry/O75376" rel="nofollow noreferrer">https://alphafold.com/entry/O75376</a>) and loaded it into Pymol (2.3.0). There is quite a large portion of the structure that was modelled with very low confidence (pLDDT &lt; 50). Is there a way to select these regions in the structure so that I can assign a different representation to them? Thank you.</p>

I have downloaded a predicted structure from AlphaFold as a pdb file (<https://alphafold.com/entry/O75376>) and loaded it into Pymol (2.3.0). There is quite a large portion of the structure that was modelled with very low confidence (pLDDT < 50). Is there a way to select these regions in the structure so that I can assign a different representation to them? Thank you.

They are stored as b-factors. This is well described in the [PyMol wiki](https://pymolwiki.org/index.php/Selection_Algebra).
