panda1982 / cwf_denoise Goto Github PK

This is a MATLAB package for denoising CTF -affected cryo-EM images based on the following manuscripts:
1) Denoising and Covariance Estimation of Single Particle Cryo-EM Images
Tejal Bhamre, Teng Zhang, Amit Singer
http://arxiv.org/abs/1602.06632

2) Fast Steerable Principal Component Analysis
Zhizhen Zhao, Yoel Shkolnisky, Amit Singer
http://arxiv.org/abs/1412.0781

The folder kn_rankest includes code for rank estimation by S. Kritchman and B. Nadler.

DEPENDENCIES
----------------

This package should be used in conjunction with the cryo-EM tool box ASPIRE (http://spr.math.princeton.edu/) and will be included in the latest version of ASPIRE. It also requires the NUFFT package (to be included in the latest version of ASPIRE) available
at http://www.cims.nyu.edu/cmcl/nufft/nufft.html.

INSTRUCTIONS
----------------

1) Download and install ASPIRE from http://spr.math.princeton.edu/ following the instructions for installation.
2) Add ASPIRE files in your MATLAB path using initpath.m in ASPIRE.
3) If this package is in a separate location than ASPIRE, add the package to your MATLAB path using cwf_paths.m  
4) Enjoy the example simulation scripts in cwf_scripts to denoise images.
