usage: prog [options] input.mrc Helps to visually assess large images using localized power spectra. Generally this is used with scanned images to look for position dependent MTF due to film flatness problems or problems with the scanner optics. However it may also be suitable for looking for images with charging or other drift/astigmatism issues. Boxes a grid pattern of areas (default 256x256), calculates a power spectrum for each area, then reinserts in the image, with a gap between them so the micrograph is still visible in the background.
| Option | Type | Description |
|---|---|---|
| --version | None | show program's version number and exit |
| --box, -S | int | size in pixels of the power spectra |
| --norm, -N | None | Normalize the image before analysis |
| --nopad | None | No padding between boxes |
| --ppid | int | Set the PID of the parent process, used for cross platform PPID |
| --verbose, -v | int | verbose level [0-9], higher number means higher level of verboseness |
