abstract = {Large-scale scientific imaging datasets -ranging from
terabytes to petabytes- are increasingly central to
neuroscience and other scientific fields. These datasets
require heterogeneous tools for analysis and visualization,
which impose conflicting requirements on file formats,
metadata schemas, and storage access patterns. Converting
between formats or duplicating data is a common workaround,
but this introduces inefficiencies, storage overhead, and
potential errors in large-volume workflows.We present
tiamat, the Tiled Image Access and Manipulation Toolkit, a
flexible and extensible Python framework that facilitates
reading, transforming, and exposing large image datasets
through a configurable pipeline of readers, transformers,
and interfaces.Tiamat supports on-the-fly transformations
such as normalization, axis reordering, and colormapping,
while streaming data to diverse endpoints—including
Napari, Neuroglancer, OpenSeadragon, Python/Numpy scripts,
and FUSE—without requiring intermediate file conversion or
duplication. We demonstrate its use within the EBRAINS
platform, where tiamat delivers 1µm-resolution histological
brain images from the BigBrain dataset directly from
high-performance GPFS storage to web-based viewers and
analysis clients.Tiamat decouples data storage from
visualization and analysis workflows, enabling modular,
reusable, and domain-agnostic image processing pipelines.Its
plugin-based design and compatibility with multiple tools
offer a scalable solution for managing large scientific
image datasets. Tiamat is implemented in Python, released
under the Apache 2.0 license, and deployed via docker. The
source code is available here.},
