pyFAI-recalib - Deprecated
DESCRIPTION
usage: pyFAI-recalib [options] -i ponifile -w 1 -c calibrant.D imagefile.edf
Calibrate the diffraction setup geometry based on Debye-Sherrer rings images with a priori
knowledge of your setup (an input PONI-file). You will need to provide a calibrant or a
"d-spacing" file containing the spacing of Miller plans in Angstrom (in decreasing order).
Calibrants available: Ni, CrOx, NaCl, Si_SRM640e, Si_SRM640d, Si_SRM640a, Si_SRM640c,
Si_SRM640b, Cr2O3, AgBh, Si_SRM640, CuO, PBBA, alpha_Al2O3, quartz, C14H30O,
cristobaltite, Si, LaB6, CeO2, LaB6_SRM660a, LaB6_SRM660b, LaB6_SRM660c, TiO2, ZnO, Al, Au

-k, --keep
Keep existing control point and append new
The main difference with pyFAI-calib is the way control-point hence DebyeSherrer rings are
extracted. While pyFAI-calib relies on the contiguity of a region of peaks called massif;
pyFAI-recalib knows approximatly the geometry and is able to select the region where the
ring should be. From this region it selects automatically the various peaks; making
pyFAI-recalib able to run without graphical interface and without human intervention
(--no-gui and --nointeractive options). Note that `pyFAI-recalib` program is obsolete as
the same functionnality is available from within pyFAI-calib, using the `recalib` command
in the refinement process. Two option are available for recalib: the numbe of rings to
extract (similar to the -r option of this program) and a new option which lets you choose
between the original `massif` algorithm and newer ones like `blob` and `watershed`
detection.
