XAID:
Software tools for visualization and analysis of XAFS spectra

XAID is a user-friendly package to perform XAFS data analysis. It is intended for visualization, averaging, extraction, filtering, etc. of single or multiple sets of raw data. For a more sophisticated analysis, including fitting to a model or ab-initio calculations, other codes should be used. See the XAFS Software Catalog and chose your preferred code.

## Modules for standard XAFS analysis:

- XAID_MU2CHI EXAFS signal Extraction
- XAID_FF Fourier Filtering
- XAID_CALIB Calibration of dispersive XAFS spectra

## Modules for multiple spectra analysis

- EXODUS Visualization, interpolation, reesampling, averaging, linear combination and fit from multiple spectra contained in SPEC data files. This module has been especially written for ID26.
- DELIA Simultaneous visualization, interpolation, calibration, extraction and Fourier filtering on a bunch of spectra (typically dispersive XAFS experiments). This module has been especially written for ID24.

## DABAX tools

- Tables of atomic scattering factors f1 and f2
- McKale phases
- EXAFS spectra database
- XANES spectra database

### Starting the program

If you are at ESRF (www.esrf.fr), the programs are installed in the NICE cluster and may be accessed by any workstation. For that enter (this command is also good for any Unix installation):
xop xaid
or (in case this fails):
/sware/exp/xop-2.0/xop xaid
If XAID starts correctly, a window like this one should appear:

From this window you should start the different XAID modules using the Start... menu.

### Installation

XAID can be freely installed in virtually any kind of machine. It is distributed as a part of the XOP software package. Two steps must be followes (see XOP website /www.esrf.fr/computing/scientific/xop)

1. Download and install XOP
2. Download and install XAID as an "XOP extension"
