A suite of GUI programs written in MATLAB for advanced data collection and anal. of full-field transmission X-ray microscopy data including mosaic imaging, tomog. and XANES imaging is presented. Transmission X-ray microscopy (TXM) has been well recognized as a powerful tool for non-destructive investigation of the three-dimensional inner structure of a sample with spatial resolution down to a few tens of nanometers, especially when combined with synchrotron radiation sources. Recent developments of this technique have presented a need for new tools for both system control and data anal. Here a software package developed in MATLAB for script command generation and anal. of TXM data is presented. The first toolkit, the script generator, allows automating complex exptl. tasks which involve up to several thousand motor movements. The second package was designed to accomplish computationally intense tasks such as data processing of mosaic and mosaic tomog. datasets; dual-energy contrast imaging, where data are recorded above and below a specific X-ray absorption edge; and TXM X-ray absorption near-edge structure imaging datasets. Furthermore, anal. and iterative tomog. reconstruction algorithms were implemented. The compiled software package is freely available.
