LIVIA: a browser-based tool for assessing and visualizing predicted protein interactions
LIVIA is a freely available, browser-based tool that locally computes local confidence metrics, identifies interface residues, and visualizes predicted protein-protein interactions across multiple platforms using an interactive 3D viewer and exportable scripts for ChimeraX and PyMOL.

Imagine you have a team of expert architects (the prediction tools) who have just designed a blueprint for how two giant Lego structures (proteins) might snap together. While these blueprints are amazing, they come with a problem: they are often complex, hard to read, and it's not always clear exactly where the two pieces are supposed to touch or how confident the architects are about that connection.
LIVIA is like a smart, friendly translator and tour guide that you can open right in your web browser to make sense of these blueprints. Here is how it works, using simple comparisons:
- The Universal Translator: Different architects speak different "languages" (file formats). LIVIA is like a polyglot that instantly understands all of them. You don't need to be a computer expert to prepare your files; LIVIA just reads them automatically.
- The "Trust Meter": When the architects say, "These two pieces fit here," LIVIA acts like a quality inspector. It runs a quick check to give you a "confidence score" for every specific spot where the proteins might touch. It tells you, "We are 90% sure this part connects," or "This part is a bit shaky."
- The 3D Tour: Instead of staring at a flat list of numbers, LIVIA opens a window with a spinning, interactive 3D model (powered by a tool called Mol*star). You can grab the model with your mouse, spin it around, and zoom in to see exactly where the proteins are predicted to hug each other.
- The Local Workshop: The best part is that LIVIA works entirely inside your own computer's "workshop." It doesn't send your data out to a remote server. It does all the heavy lifting and math right on your machine, keeping your data private and safe.
- The Blueprint Exporter: If you want to show off your findings to a colleague using other professional software (like ChimeraX or PyMOL), LIVIA can instantly write the "instructions" (scripts) for you to do that, saving you from typing them out manually.
In short, LIVIA takes the complicated, raw data from protein prediction tools and turns it into a clear, interactive, and trustworthy visual story that anyone can explore in their browser, without needing to install complex software or send their data anywhere else.
