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!

Don't know much about Shiny, but as its web based, can you make use of JSmol/Jmol or something?

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

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 :)

xoxo

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 :)
