Dear Abril, you can stretch the chain using the *ISOLDE* software, which is available as a tool within ChimeraX. More info at the website: https://tristanic.github.io/isolde/index.html Enjoy!

Hi Elaine,

I have this alphafold structure (see picture) that is basically a huge string/thread and then a folded domain. I wanted to stretch the string to make its length more obvious. Is it possible to pull the residues without messing with the connections (peptide bond)? I am using chimeraX and I saw that you can "move atoms" but when you pull one you don't pull the others. If chimera cannot do this, do you know if another program will allow me to do it?

Thank you in advance for your help, Best regards, Abril Gijsbers
