Single-molecule localization microscopy (SMLM) has had remarkable success in imaging cellular structures with nanometer resolution, but standard analysis algorithms necessitate the activation of only single isolated emitters which limits imaging speed and labeling density. Here, we overcome this major limitation using deep learning. We developed DECODE, a computational tool that can localize single emitters at high density in 3D with highest accuracy for a large range of imaging modalities and conditions. In a public software benchmark competition, it outperformed all other fitters on 12 out of 12 data-sets when comparing both detection accuracy and localization error, often by a substantial margin. DECODE allowed us to take fast dynamic live-cell SMLM data with reduced light exposure and to image microtubules at ultra-high labeling density. Packaged for simple installation and use, DECODE will enable many labs to reduce imaging times and increase localization density in SMLM.
The datasets included here are used to extensively test and compare the performance of DECODE for a wide variety of different recording techniques and conditions.
Includes several sets of simulated data that can be used to evaluate the performance of localization algorithms.
Metrics_Density_X are simulations with different emitter densities (Fig. 2c,d,e) and Signal to Noise Ratios (SNR, Fig. 2c).
CRLB_SNR are simulations of isolated emitters used for comparisons with the Cramér–Rao bound (Fig. 2a)
RMSE_Sigma_corr are simulations of repeated samples of the camera model for identical emitter parameters to test the uncertainty estimates of DECODE (Fig. 2b).
All localizations and evaluations are collected in Fig2_collect_5.hdf5 and can be accessed as shown in Fig_draft_upload.ipynb.
The same sample of microtubules, labeled with anti-α tubulin primary and AF647 secondary antibodies, imaged with different UV activation intensities to resulting in different emitter densities per frame and acquisition times between 93 and 1120 s, while keeping the total number of localizations the same. Used to evaluate the performance of localization algorithms across emitter densities (Fig. 4a,b,c).
