Convert SILO to NWB Online - Free & Fast

What is SILO?

SILO is a portable file format developed at Lawrence Livermore National Laboratory for storing multi-dimensional mesh and field data, supporting structured grids, unstructured meshes, and point data for large-scale scientific simulations.

What is NWB?

Neurodata Without Borders (NWB) is a data standard built on HDF5 for organizing and sharing neuroscience experiments, consolidating electrophysiology, optical physiology, behavior, and metadata into a single self-describing file.

When Should You Use SILO vs NWB?

SILO vs NWB: Key Differences

• •SILO and NWB diverge on compression: lossy compression for the source, lossless compression for the target.
• •Moving from SILO (lossless) to NWB (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Alpha channel support: NWB lacks transparency support.
• •File sizes: SILO files typically range 100MB to tens of GB per simulation step and NWB files 100MB to 2TB per experiment depending on modalities.
• •Use case fit: SILO targets petascale simulation data, hydrodynamics, hpc visualization and NWB targets extracellular electrophysiology, optical physiology, multi-modal neuroscience — your choice depends on which workflow stage you are serving.

Advantages of SILO

• ✓The lossy nature of SILO means file sizes stay reasonable while handling Petascale simulation data, hydrodynamics, HPC visualization efficiently.
• ✓From mobile devices to enterprise servers, SILO is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using SILO thanks to its efficient compression.
• ✓SILO is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of NWB

• ✓NWB uses lossless compression tailored for Extracellular electrophysiology, optical physiology, multi-modal neuroscience.
• ✓NWB is supported natively on virtually every device, browser, and operating system.
• ✓NWB files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓NWB integrates seamlessly with all major creative tools and workflows.

Common Use Cases for SILO to NWB Conversion

Industry Applications

Best Practices for SILO to NWB Conversion

• →When converting SILO to NWB: verify that variable names, units, and dimensions are preserved
• →Preserve metadata and provenance attributes so NWB remains scientifically interpretable
• →Check that multi-dimensional arrays (time, depth, lat, lon) map without truncation
• →Confirm endianness and numeric precision are handled correctly for the target format output
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting SILO to NWB Conversion

• !NWB loses variables or dimensions converting from SILO → check that the target format supports the same rank/shape of arrays
• !Units or scale look wrong in NWB → verify scaling factors and offset attributes were applied during SILO to NWB
• !Metadata stripped from NWB output → preserve global and variable attributes for reproducibility
• !SILO to NWB fails for large files → chunk the dataset or increase available memory before converting
