Sample scans for the XCT toolchain accompanying the paper "X-ray micro-CT pipeline for large-scale tree-ring densitometry studies"

Sample scan files accompanying the pipeline described in the paper "X-ray micro-CT pipeline for large-scale tree-ring densitometry studies" These are sample files to test out the XCT toolchain, hosted on the github repository for the compiled XCT toolchain software suite. Check GitHub for the latest version. It consists of three executable programs: CoreProcessor, which extracts individual cores from scans and converts them to absolute density values; RingIndicator, designed for semi-automatic ring indication and density profile calculation; and CoreComparison, which facilitates cross-dating. The packages are compiled for Microsoft Windows, and require the free installation of MATLAB Runtime (currently version 2024b). The output of indications and density profile calculations are in txt format and can be loaded and manipulated in R using the XCT.Read function. More info and comprehensive written and video manuals are available for free at our site and in this paper. This is part of a pipeline available in the 2025 Dendrochronologia paper "X-ray micro-CT pipeline for large-scale tree-ring densitometry studies" by Verschuren and co-authors.
