Peaksearch is a program written in Python by Jon Wright (esrf.eu) to search peaks in 2D diffraction images.

Options

The most current options can be obtained by selecting PeakSearch | Options | PeakSearch Command-Line Options from the main menu . These were the options when this page was written:

option, or full option description
-h , --help Show this help message and exit
-n STEM , --namestem=STEM Name of the files up the digits part, e.g. mydata in mydata0000.edf
-F FORMAT, --format=FORMAT Image File format, e.g. edf or bruker
-f FIRST, --first=FIRST Number of first file to process, default=0
-l LAST, --last=LAST Number of last file to process
-o OUTFILE, --outfile=OUTFILE Output filename, gets extension .spt
-d DARK, --darkfile=DARK Dark current filename, to be subtracted, default=None
-D DARKOFFSET, --darkfileoffset=DARKOFFSET Constant to subtract from dark to avoid overflows, default=100
-s SPLINE, --splinefile=SPLINE Spline file for spatial distortion, default=/data/opid11/inhouse/Frelon2K/spatial2k.spline
-p PERFECT, --perfect_images=PERFECT Ignore spline Y|N, default=N
-O FLOOD, --flood=FLOOD Flood file, default=None
-t THRESHOLDS, --threshold=THRESHOLDS Threshold level, you can have several
-S OMEGASTEP, --step=OMEGASTEP Step size in Omega when you have no header info
-T OMEGA, --start=OMEGA Start position in Omega when you have no header info
--ndigits=NDIGITS Number of digits in file numbering [4]
-P PADDING, --padding=PADDING Is the image number to padded Y|N, e.g. should 1 be 0001 or just 1 in image name, default=Y
--OmegaFromHeader Read Omega values from headers [default]
--OmegaOverRide Override Omega values from headers

ImageD11
ImageD11 is a software package for analysis of 2D diffraction images. The package includes:
  1. peaksearch,
  2. transformer to compute g-vectors,
  3. fitgrain to refine of diffractometer geometry,
  4. filtergrain to indexing grains
  5. fft_index.py to index large unit cells,
  6. Some useful tools like edf2bruker.py and bgmaker.py,
  7. and fit2cake to carry out radial integration of series of images.
