Sharpening emitter localization in front of a tuned mirror - NPC dataset

This is a depository for two single molecule localisation microscopy datasets of nuclear pore complex (NPC) structures for single particle averaging. The data was published in: 

Heil, H.S., Schreiber, B., Götz, R. et al. Sharpening emitter localisation in front of a tuned mirror. Light Sci Appl 7, 99 (2018). https://doi.org/10.1038/s41377-018-0104-z

Both datasets have two different levels of localisation precision as one is a conventional STORM experiment and the second a mirror-enhanced STORM experiment. A detailed description of the sample preparation and imaging conditions can be found in the related publication. In short the NPC structures are placed on the surface of a glas coverslip or nano-mirror coated coverslip by manual isolation and spreading of nuclear envelopes from xenopus laevis oocytes, fixed and stained by indirect immunolabeling. The primary antibody targets GP210, the secondary F(ab')₂ fragment is conjugated with Alexa Fluor 647. 

In this depository I'm providing the raw images data, localisation data and super-resolved reconstruction  for the two experiments, as well as the localisation data and super-resolved reconstruction of single NPC rings. 

I'm also providing a MatLab script that allows to select single NPC positions in the super-resolved image and export the localization data of the single NPC ROI: P01_ImageAlignment_PickElements.m

Information about the dataset is also available  here: NPC Image Alignment Dataset_Info.pdf.

Image parameters: 102 nm pixel size, EM Gain 100, Photoelectrons per A/D count: 15.01

Column structure of the localisation text files: 

Id,Frame, x [nm], y [nm], sigma [nm], intensity [photon], offset [photon], bkgstd [photon], chi2, Uncertainty [nm], detections
