bookmark BDV / BigDataViewer A re-slicing browser for terabyte-sized multi-view image sequences. BigDataViewer was developed with multi-view light-sheet microscopy data in mind and integrates well with Fiji's SPIMage processing pipeline. Conceptually, the visualized data comprises multiple data sources. Each source provides one 3D image (for each time-point in the case of a time-lapse sequence). For example, in a multi-angle selective plane illumination microscopy (SPIM) sequence, each angle is a source. In a multi-angle, multi-channel SPIM sequence, each channel of each angle is a source. BigDataViewer comes with a custom data format that is optimized for fast random access to very large data sets. This permits browsing to any location within a multi-terabyte recording in a fraction of a second. The file format is based on XML and HDF5. Images are represented as tiled multi-resolution pyramids, and stored in HDF5 chunked multi-dimensional arrays. The XML file contains metadata, for example the registration of sources to the global coordinate system.
