| This logic can estimate ctf parameters from particle power spectra class sums, apply previously calculated ones to images and also lets the user choose the parameters manually. This correction for the phase information modulation during the imaging process is an essential part of getting high resolution structures out of input data. | This logic can estimate ctf parameters from particle power spectra class sums, apply previously calculated ones to images and also lets the user choose the parameters manually.

| - | In this paragraph, the "HOW a logic works under the hood" and WHY someone should use it can be elaborated with higher detail. Describes a scenario in an image processing workflow where this logic can be used to solve the resulting problem. Also, wikipages, publications or anything else describing the theory behind an algorithm should be linked here, if applicable. | + | This method of ctf correction is based on a paper from the stark lab [[http://www.sciencedirect.com/science/article/pii/S1047847703000728|paper from the stark lab ]] |
