read Zwick zs2 and zp2 files

Project description

https://travis-ci.org/cpetrich/zs2decode.svg?branch=master

zs2decode is a Python (2.7, 3.3, 3.4, 3.5, 3.6) implementation of a decoder for Zwick zs2 files.

zs2 files contain measurements and meta data. zs2decode is able to parse these files. It contains support functions to output the result as text file or XML for further processing. The following script converts a zs2 file into XML:

import zs2decode.parser
import zs2decode.util

zs2_file_name = 'my_data_file.zs2'
xml_output_file = 'my_data_file.xml'

# load and decompress file
data_stream = zs2decode.parser.load(zs2_file_name)
# separate binary data stream into chunks
raw_chunks = zs2decode.parser.data_stream_to_chunks(data_stream)
# convert binary chunk data into lists of Python objects
chunks = zs2decode.parser.parse_chunks(raw_chunks)
# output as text file
with open(xml_dump_file, 'wb') as f:
    f.write( zs2decode.util.chunks_to_XML(chunks) )

An example script to extract measurement time series from the XML is provided in the examples folder.
