xylib is a portable library for reading files that contain x-y data from powder diffraction, spectroscopy and other experimental methods.
It comes with two programs that can convert supported formats to plain text: command-line xyconv and graphical xyconvert.
- plain text, delimiter-separated values (e.g. CSV)
- Crystallographic Information File for Powder Diffraction (pdCIF)
- Siemens/Bruker UXD
- Siemens/Bruker RAW ver. 1/2/3/4
- Philips UDF
- Philips PC-APD RD raw scan V3/V5
- PANalytical XRDML
- Rigaku DAT
- Sietronics Sieray CPI
- DBWS/DMPLOT data file
- Canberra CNF (from Genie-2000 software; aka CAM format)
- Canberra AccuSpec MCA
- XFIT/Koalariet XDD
- RIET7/LHPM/CSRIET/ILL_D1A5/PSI_DMC DAT
- Vamas ISO14976 (only experiment modes: SEM or MAPSV or MAPSVDP are supported; only REGULAR scan_mode is supported)
- Princeton Instruments WinSpec SPE (only 1-D data is supported)
- χPLOT CHI
- Ron Unwin's Spectra XPS format (VGX-900 compatible)
- Freiberg Instruments XSYG (from lexsyg)
- Bruker SPC/PAR
Examples of supported files are collected in sample-urls.
The library is written in C++11 and has C bindings.
R bindings: rxylib (CRAN) by Sebastian Kreutzer.
Python bindings: pip-installable, generated by SWIG, details below.
Other languages (suggestions): you may access C API through FFI (here is an example), or extend xylib.i to wrap the C++ interface using SWIG.
Licence: LGPL 2+
xylib is used by:
Converts a file from one of the supported formats to plain text:
xyconv myfile.bin plain.txt
It has a few options, see
xyconv -h for details.
The GUI is designed for quick converting of many files at once.
To compile the source code you need:
- C++ compiler (all popular ones are tested: GCC, Clang, MSVC, icc)
- Boost libraries >= 1.46.1 (only headers).
- optionally, zlib and bzlib libraries (for reading compressed files)
- optionally, wxWidgets 3.0 (for xyconvert - GUI converter)
Two build systems are provided: either use CMake or, on Unix,
./configure && make. To skip building the GUI use option
-D GUI=OFF for CMake or
--without-gui for configure.
If you are using git,
autoreconf -i is needed before
Python bindings require SWIG, Boost headers and a C++ compiler. It may be enough to just type:
pip install xylib-py --user
If the Boost headers cannot be found, run pip with options
xyconv.py file for usage examples.
