Figure 2
Instant-NGP trains fast. Resolution of the TRPV1 ion channel using instant-NGP versus various real-spaced representations for synthetic data (10 000 particles). Volume resolution, measured with the Fourier shell correlation (FSC), is shown as a function of the gradient-training steps for varous real-spaced volume representations. All representations have a similar number of training parameters (∼20 000), except for the voxel representation which has 4.1 million, ∼20× more. The FSC was calculated against the reference structure from which the synthetic data was generated, with a threshold value of 0.5 used to estimate the resolution. Example 3D volumes are shown at the indicated time points (A, B, C, D and E). |
