Hi William,<br>
The "&" is wrong -- that symbol is for intersection, and the intersection between the two different models is nothing (none of the atoms are in both #1 and #2 at the same time). I.e. to specify both models together try #1,2 instead:<br>
<br>
alphafold predict #1,2<br>

past few months to elucidate possible protein structure for one of the protein I am currently studying. I have faced a problem with predicting a protein interaction between a heterodimer (6z1n) and a novel protein that I am studying now. When I loaded both
pdbs, I am unable to run the alphafold via the command:<br>

between the2 monomers within 6z1n instead?<br>
