Tomographic data supporting the article: Microstructural design of the stalk in the crinoid Seirocrinus supports its pseudoplanktonic lifestyle

Raw tomographic data associated with the article: “Microstructural design of the stalk in the crinoid Seirocrinus supports its pseudoplanktonic lifestyle” https://www.nature.com/articles/s41598-025-16412-8TXM/TXRM (Transmission X-Ray Microscopy ) are proprietary microscopy data files created by ZEISS 3D X-Ray Microscopes (microCT systems). Tomography datasets that contain a collection of projections (2D images acquired at different angles around the axis of rotation) were saved as *.txrm file. Then, Reconstructor manually reconstructed images stored in *txrm file to form a set of reconstructed slices. A slice is a 2D section of the 3D reconstructed volume that is oriented in the X/Z plane. Slices generated from *.txrm file are stored in a *.txm file. 1TXM/TXRM post-processing software:Open Xradia - plugin for Fiji (ImageJ) for reading XRM, TXRM, TXM image files (from Xradia XRM systems), opens them as a stack.(https://forum.image.sc/t/open-xradia-zeiss-microct-xrm-files-in-fiji/44466)Dragonfly-Pro – visualization and analysis software using Python scripting exclusively from ZEISS.Thermo Scientific Avizo Software for 3D visualization, analysis, and measurements of features of interest from imaging data.TXM3DViewer – ZEISS software for viewing and analyzing 3D volumetric data.(1) according to ZEISS Xradia Versas User Guide, File and File Storage, 2014-2016
