Inside Studio

From structure to insight,
in one place

Structure preparation

Fetch a PDB or an AlphaFold DB model, complete missing atoms and residues and add hydrogens with PDBFixer.

Molecular dynamics

Solvation, minimization, NVT/NPT equilibration and production with OpenMM (Amber14), or your own GROMACS inputs. CUDA, OpenCL or CPU.

Docking

Dock small molecules with AutoDock Vina: SMILES or SDF/MOL2 ligands, a box around the crystal ligand, a manual box or blind docking.

Workflows & batches

Chain steps from a template (prepare → minimize → equilibrate → MD → analysis) and run the same tool over many inputs at once.

Structure viewer

A PyMOL-style viewer with commands, selections and measurements. Export PNG up to 4×, 360° MP4 videos or a PyMOL session script.

Projects, API & AI

Every job is tracked in projects with its full lineage. Drive Studio from scripts (REST API) or from AI assistants such as Claude (MCP).

Built in · free

Analyses, next to the viewer

Open a structure in Studio's viewer and run one-click analyses from the side panel. They run in your browser and cost nothing; anything you find can go straight into a docking or simulation job.

Binding pockets

Find the pocket around a bound ligand, or predict the most likely one from burial and concavity, with a druggability score.

Mutagenesis

Swap any residue for one of the 20 amino acids with rotamer selection and a clash report. The mutant opens as its own object.

Interactions

2D ligand interaction maps, chain–chain interfaces (H-bonds, salt bridges, hydrophobic and aromatic contacts) and salt bridges.

Superposition

Fetch a second structure by PDB ID and superpose it onto yours; the RMSD and matched atom count are reported.

Flexibility

A Gaussian network model predicts per-residue flexibility and colors the structure from rigid to flexible, compared against B-factors.

And more

Ramachandran plots, H-bond networks, contact maps, a B-cell epitope finder, UniProt and STRING lookups — plus a drug-discovery tab that sends ligands to real AutoDock Vina docking and screening jobs.

How it works

Four steps from structure to insight

No cluster tickets. Add your computer once with a single command; Studio sends it the jobs and keeps the results.

Open Studio →
1

Add your computer

Run one command on Linux, Windows or macOS. Engines like docking install themselves the first time you use them.

2

Pick a tool or workflow

Start from a PDB ID, an AlphaFold model or your own file; chain steps into a workflow or run a batch.

3

Simulate & analyze

Your GPU or CPU does the work; results, structures and trajectories are stored in your account.

4

Explore & export

Inspect results in the viewer, organize them in projects and export images, videos and structures.
