SDPCHAIN

Seismology Data Preparation Module

Routines and classes providing a consistent interface for Python programs using the SDPCHAIN protocol, which includes:

• Create or append to a process-steps.json file at each step

  • the process-steps file is read from the input directory and written to the output directory. If both directories are the same the new step is appended to the existing file

• command-line arguments:

  • -d (base_dir)
  • -i (in_dir), can be relative to base directory
  • -o (out_dir), can be relative to base directory
  • optional (input_file) or (input_files), will have input directory pre-pended
  • optional -of (output_file) or -ofs (output_files), will have output dir pre-pended
  • optional -f, forces writing of output file if it already exists

• For now, these parameters must have exactly the above names in the files that use SDPCHAIN, so that setup_paths and ProcessStep process them correctly. The new ArgParser subclass should eliminate this need, but pre-populating the argparser with base_dir, in_dir and out_dir, as well as optionally input_file or input_files, output_file or output_files, and/or -f

Classes

ProcessSteps object to hold information for a process-steps file

Command-line Routines

These routines perform common functions while following the SDPCHAIN rules (process-steps file, -i, -o, -d)

sdpstep: run a standard command-line program

sdpcat: concatenate binary files

ToDo

Add sdpcode: change net and station codes?
