Re: [PyMOL] Structure alignment -- general question

[Ali S. K. <aku...@un...>]

Hi George,

You can do pairwise alignments, i.e. align 3 of the structures to one structure.

You can also use the "extra_fit" method (https://pymolwiki.org/index.php/Extra_fit), i.e:

extra_fit name CA, "object", super

Replace object with the structure you want the other 3 to align to, this uses the "super" alignment method but you can also use "align", "cealign", "fit", etc. Depending on what gives the best results. Just a note, this will align all PyMOL objects to your selected object, you can make sub selections as needed.

Cheers,

Ali

    I’m dealing with 4 heterogeneous structures belonging to the same fold. I’d like to compare some conserved structural features and for this purpose it would be useful that the structures are aligned and then visualised in a grid.

    I understand that the align command works for 2 structures only. Is there another way achieve what I described above.

    Looking forward to any suggestions

    Many thanks in advance and all the best for 2022
