- | THIS position should be used for a brief introduction (max 2 sentences!) of the logic, stating WHAT and WHY it is doing something. | + | Here, a set of arithmetic operations are described, which all use full images as input. If a stack of images is used, the operation is carried out per-image. |
- | + | ||
- | ===== Usage ===== | + | |
- | Here, a general/generic description of HOW the logic is USED should be given. Try to be as general as possible, but also mention prerequisites, restrictions, advantages, requirements which are specific of this logic. Basically everything the user needs to know to successfully use this logic. | + | |
- | + | ||
- | ===== Example ==== | + | |
- | Here, a very specific example should be given/described. In the future, this can be supported by screenshots etc.. For the moment, give an example easy enough for the user to understand, but specific enough to elaborate why a given parameter is a good set for this very situation. | + | |

- | | Mode | FIXME Can be set to either 'notional' or 'direct': The notional mode generates an artificial power spectrum either based on information from the header or stated by the user (see parameter 'Use ctf information from image header' below), that is used while averaging. In direct mode, the power spectrum is calculated directly from the input data. | | + | | Mode | Can be set to either 'notional' or 'direct': The notional mode generates an artificial power spectrum either based on information from the header or stated by the user (see parameter 'Use ctf information from image header' below), that is used while averaging.
