A structure won't load

The most common cause is an unsupported or mismatched format. Check that your file is one of the supported types in Supported file formats. You can also try loading a structure by its PDB ID.

Large trajectories are slow

The viewer streams and optimizes large trajectories automatically, but very large ones still take time. Use Preview mode first to scrub quickly, then switch to full quality once you've found the part you want. See Trajectories.

I'm a guest and can't load a structure

That's expected. In a shared session, guests are read-only followers — you can watch and chat, but only the host can load structures and control playback.

My upload was rejected

Two common reasons:

Storage is full. Free up space or upgrade your plan — see Storage & quotas.
The format isn't supported. Confirm the file type in Supported file formats.

My image snapshot is missing its annotations

Annotations are an on-screen overlay, so they aren't part of the rendered 3D image and won't appear in an exported snapshot.
