mca2edf(1) PyMca X-Ray Fluorescence Toolkit mca2edf(1)NAME
mca2edf - Convert SPEC file format files to EDF format
SYNOPSIS
mca2edf [OPTIONS] [FILES]
DESCRIPTION
X-ray maps were stored at the European Synchrotron Radiation Facility as a set of images in ESRF Data Format (EDF). The image rows being
associated to points of a horizontal sample scan and the image columns to the spectrum channels.
This tool allows to convert a set of files wrapped by the PyMca Toolkit as SPEC file format, and therefore without sample position informa-
tion, to European Synchrotron Radiation Facility data format (EDF).
Its usefulness is nowdays somehow limited because recent PyMca developements allow to reshape nspectra x nchannels datasets in the tools
making use of the shape information (pymcaroitool, pymcapostbatch).
EXAMPLES
mca2edf
Open a dialog to select input files, output directory and the
number of spectra on each horizontal row.
mca2edf --outdir=/tmp --mcastep=2 *.mca
Convert all the .mca files in current directory to a set of EDF
files containing two spectra. The output is placed in /tmp
mca2edf --outdir=/tmp --mcastep=2 --listfile=input_file
Same as before but applied to all the files listed in input_file.
Each line of input_file must contain a valid file name.
