Code2Fold Studio structure viewer showing HIV-1 protease with docked indinavir and a Ramachandran plot

A real Studio session: HIV-1 protease (PDB 1HSG) with indinavir docked by AutoDock Vina, and a Ramachandran plot in the Analyses panel.

The challenge

Computational structural biology should not need a cluster and a week of setup

Expensive infrastructure

MD simulations and docking need GPUs and specialized software that many labs cannot justify for occasional use.

Fragile toolchains

Each engine has its own installation, file formats and parameters. Time goes into maintenance instead of science.

Results that get lost

Trajectories and settings end up scattered across machines, which makes work hard to repeat and share.

The platform

Everything in Studio

One account for structures, simulations, docking and analysis. These are real screens from Code2Fold Studio.

Workflows

From a PDB entry to trajectory analysis in one run

Start from a template or a blank canvas. Studio prepares the structure, minimizes it in a water box, equilibrates, runs production MD and analyzes RMSD and RMSF.

Every step's inputs and settings are saved with the result

Workflows

Docking and drug discovery

Dock ligands next to the structure you are looking at

Fetch a ligand, set the docking box around the pocket and start AutoDock Vina from the viewer. Poses come back as structures you can inspect, compare and send to MD.

Your workspace

Every result and its settings, kept in your account

Jobs run free on your own computer and its GPU, with temperature and load limits that protect the machine. Results, settings and history are saved to your Code2Fold account, so you can pick up from any device.

Measured, not promised

Production MD speed on a laptop GPU

Explicit-solvent production MD with OpenMM on an NVIDIA RTX 4050 Laptop GPU, measured end to end in Studio.

650ns/day

Crambin (1CRN)

46 residues, solvated

452ns/day

Ubiquitin (1UBQ)

76 residues, solvated

170ns/day

HIV-1 protease (1HSG)

Dimer, 198 residues, solvated

Production step only; preparation, minimization, equilibration and analysis add seconds to a minute for these systems. Data-center GPUs are typically faster.
