HDF5 Slice Desk
A bounded scientific data desk for local HDF5 inspection. Select a dataset and explicit axis ranges while retaining the metadata needed to interpret the extracted values.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
