Forum:How to calculate LDDT score for protein structure ?

Question

[aaggencc]

I am using molecular dynamic simulation and would like to measure LDDT score for protein structure. There is an online server for doing this but I couldn't find any python code to do it as I am using an open-source molecular simulation. Is there any python code to do this?

No python code that I am aware of, but Linux and MacOS binaries can be downloaded from the two links below.

• https://openstructure.org/static/lddt-linux.zip
• https://openstructure.org/static/lddt-macosx.zip

Maybe you'd want to read this as well:

Thank you so much for replying. Especially do you know any place where to calculating IDDT score for complex proteins?

Is that correct that lDDT only calculate the first chain? So do you need to assign the complex with a same chain ID?
