This package of MATLAB routines with accompanying GUI allows scientific users to measure the 3D location of single molecules when using the double-helix point spread function (DH-PSF) widefield microscope. Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs

The open source software sdmixer reconstructs a TIFF image from a single molecule localization data set. The spectral demixing option allows multi color super resolution microscopy. sdmixer supports multipage TIFF images and is able to process large 3D data sets. Further features are 2D/3D convolution, histogram based contrast enhancement and nearest neighbor analysis.

...Perform a phase retrieval algorithm based on maximum likelihood estimation (MLE) of a phase aberration term which is added to the theoretical pupil function of the imaging system. 3. Use the phase-retrieved pupil function to perform single-emitter localization. Accompanying publication available here: https://doi.org/10.1364/OE.25.007945

The Electron Pair Localization Function (EPLF) helps to understand chemical bonding in molecular systems. This code uses a modified formulation which allows the exact calculation of the EPLF for usual wave functions (HF,KS,CAS,...)
