when you load a pdb file, open the console. It will say, "found biomolecule 1: [something]". the number of letters is the number of chains. for the width question, you can type "boundbox on" and "show boundbox". you'll have to subtract all three length values and see which one is longest.Chameleon02 wrote: ↑February 15th, 2020, 12:43 amHey guys. How do I find out how many chains are in a structure?

How do I find the widest width of a protein?

How do I find how many polymers a structure contains?

Thanks!

I'm not quite sure what you mean by how many polymers, is that not the same thing as the number of chains?

Correction: the first set of coordinates is the center of the boundbox, and the second set of coordinates is the distance from the center to the outside of the box along each axis (x,y,z). to find the length, subtract and multiply by 2.
