Gold standard fourier shell correlation
WebMay 18, 2024 · To avoid overfitting, gold-standard procedures must be used during subtomogram alignment . Prior to initial alignment, the data is split into two halves. The Fourier shell correlation (FSC) between the references generated by each half dataset can be used to estimate the resolution of the references.
