Hi All!
I am creating a Shiny server and would like to show the user protein structures from PDB file. I tried to search for a package that is able to do that, but could not find one. bio3d can write the output to open by pymol and Rpdb have a visualization, but unfortunately it is not very good....
Is there any package or workaround that I am not aware of? Or any workaround if cannot be done by a package?
Thank you!

I recently released the NGLVieweR package which is a htmlwidget for the NGL.js JavaScript library. It can be used to visualize and interact with protein data bank files (PDB) in R and Shiny applications. It includes a set of API functions to manipulate the viewer after creation and makes it possible to retrieve data from the visualization into R. You can find the documentation here.

Hello :)
I tried use NGLVieweR into a shiny app but i failed.
I've a doubt: in my shiny script, user must enter with pdb file as input. How i can read and view protein structure with NGLVieweR? I only managed to use it by reading a local file or putting a pdb code. Please, help me :)

Can you post your issue and the code you tried on the NGLVieweR github page? Then I will have a look at it. Maybe also have a look at the below article that explains how file uploads work in Shiny:

Hello there! If you are still looking for an implementation for this, myself and another are developing the package {r3dmol} which has support for exactly this. Checkout the documentation here and let us know any feedback if you have particular questions or requests for features :)

Don't know much about Shiny, but as its web based, can you make use of JSmol/Jmol or something?
Thanks, I will look into it!
PV is great for this, but it's JS not R
Actually if you make use of ShinyJS you can integrate any JavaScript library quite easily in your shiny application. I don't know how the 3D animation will integrate with shiny objects though, but it is worth a try
Thank you both, I hoped to avoid messing around with JS, but these seem good.
Are you hoping to display a dynamic structure or just a static one? If it's the latter, you could perhaps simply fetch an image of the protein from PDB and display that directly?
Thank you for the answer. I have custom PDB files, I cannot just fetch unfortunately
