It is a multi-particle extension of the Fourier ring correlation (FRC), which is related to the Fourier shell correlation. The SSNR is a popular method for finding the resolution of a class average in cryo-electron microscopy. == Calculation == :$$ SSNR (r) = \frac\right|^2} \sum_\sum__}\right|^2}} -1 where $F\_$ is the complex structure Factor for image k for a pixel $r\_i$ at radius $R$. It is possible convert the SSNR into an equivalent FRC using the following formula: :$$ FRC = \frac 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spectral signal-to-noise ratio」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
