Python package to read data from TFD files used in geophysical logging.
I'm working from the incredibly helpful paper by Liang and Zhang (2015).
At the moment the header is being read in OK. Simple curve data will be next.
> pip install git+https://github.com/kinverarity1/tfdread#egg=tfdreadThe function tfdread.open() returns a TFD object with a few methods on it:
>>> from pprint import pprint
>>> import tfdread
>>> with tfdread.open(r"tests\GO7-40-FTC_26-05-16_13-17-29.tfd") as f:
... pprint(f.to_dict())
...
{'_filename': 'tests\\GO7-40-FTC_26-05-16_13-17-29.tfd',
'_structs': {'index_a': <tfdread.tfdreader.IndexA object at 0x000002A7B51A30A0>,
'index_b': <tfdread.tfdreader.IndexB object at 0x000002A7B51A34C0>,
'index_c': <tfdread.tfdreader.IndexC object at 0x000002A7B51A3518>,
'info_a': <tfdread.binary_utils.Record object at 0x000002A7B51A3570>,
'timestamp_field': <tfdread.tfdreader.IndexADate object at 0x000002A7B51A3048>},
'timestamp': datetime.datetime(2016, 5, 26, 13, 17, 29)}There's also a to_json() method, which can also be used from the command-line:
