Preprocessing tool: pyFAI-average
=================================
Purpose
-------
This tool can be used to average out a set of dark current images using
mean or median filter (along the image stack). One can also reject
outliers be specifying a cutoff (remove cosmic rays / zingers from dark)
Options:
--------
usage: pyFAI-average [options] [options] **-o** output.edf file1.edf file2.edf ...
positional arguments:
+++++++++++++++++++++
FILE Files to be processed
optional arguments:
+++++++++++++++++++
**-h**, **--help**
show this help message and exit
**-V**, **--version**
show program's version number and exit
**-o** OUTPUT, **--output** OUTPUT
Output/ destination of average image
**-m** METHOD, **--method** METHOD
Method used for averaging, can be 'mean' (default) or 'min', 'max',
'median', 'sum', 'quantiles' , 'cutoff', 'std'. Multiple filters can
be defined with ',' separator.
**-c** CUTOFF, **--cutoff** CUTOFF
Take the mean of the average +/- cutoff \* std_dev.
**-F** FORMAT, **--format** FORMAT
Output file/image format (by default EDF)
**-d** DARK, **--dark** DARK
Dark noise to be subtracted
**-f** FLAT, **--flat** FLAT
Flat field correction
**-v**, **--verbose**
switch to verbose/debug mode
**-q** QUANTILES, **--quantiles** QUANTILES
average out between two quantiles **-q** 0.20-0.90
**--monitor-name** MONITOR_KEY
Name of the monitor in the header of each input files. If defined the
contribution of each input file is divided by the monitor. If the
header does not contain or contains a wrong value, the contribution
of the input file is ignored. On EDF files, values from 'counter_pos'
can accessed by using the expected mnemonic. For example
'counter/bmon'.
**--quiet**
Only error messages are printed out
It can also be used to merge many images from the same sample when using
a small beam and reduce the spotty-ness of Debye-Sherrer rings. In this
case the "max-filter" is usually recommended.
