A Python library for seismic data processing and analysis.

PySeis is a processing-focused library for seismic data. The I/O layer has been extracted into the standalone pyseis-io library, allowing PySeis to focus on processing algorithms and workflows.

PySeis now depends on pyseis-io for all file format I/O operations. This separation provides:

• Stable I/O layer: Format readers/writers independent of processing tools
• Clean dependencies: Processing code doesn't need to know about file formats
• Reusable components: Other tools can use pyseis-io without PySeis

• pyseis-io: I/O library for seismic data formats
• Python 3.8+
• numpy, pandas, dask (via pyseis-io)

# Install pyseis-io first
cd pyseis-io
pip install -e .

# Then install PySeis
cd ../PySeis
pip install -e .

PySeis is undergoing refactoring to work with the new I/O architecture. Processing tools are being updated to use the pyseis-io data models.
