With complex-valued, multi-echo data (i.e., ME-EPI with both magnitude and phase information reconstructed), it is possible to estimate and correct for distortion on a volume-by-volume basis. I'm defi…

It would be great if center-of-mass and other functions allow for a proper scaling of the k-vectors in the diffraction pattern.
Ideally, the functions would accept a transformation matrix as an argum…

Apparently, the JF detector has the beam-center at the origin, making the pixel coordinates ranging from -2000 to +2000. The distortion correction from pyFAI does not handle this case properly

Hi,
I've followed the video and the procedure on [documentation page](https://www.repetier.com/documentation/repetier-firmware/z-probing/), however the resulting matrix has high values like that:

MIRI will benefit the most from distortion correction due to its lower pixel res (0.11 arcseconds/pixel) and smaller sub-array aperture for slitless (MIRI SLITLESS PRISM).
Distortion correct can f…

In tutorial for Dexela detector, many faulty pixels were found when calculating the LUT.

It should be possible to enable Auto Distortion Correction for a selection of images
and have RT compute the correct values for each one.

Hi,
I noticed that when using the lensfun distortion corrections, the resulting images are upsampled to the original dimensions of the raw file, which is IMO really a waste of resources and space and…

Hi all,
I'm trying to compare different ways to preprocess my data, and I'm wondering if it is possible to run only fieldmapless susceptibility distortion correction without all the other steps of fM…
