Meta-Xtract

Overview

MetaXtractor is a Python class designed to extract metadata from various file formats including:

• .h5 (HDF5)
• .xrdml (XRDML XML-based)
• .dm4 (DigitalMicrograph)
• .ibw (Igor Binary Wave)

Installation of Dependencies

pip install -r requirements.txt

Running the extractor

For h5 File type

from materials.AFM.bandexcitation.h5 import H5
import json
from pprint import pprint

process_file = H5("path/to/file")
metadata = process_file.extract()

print(metadata)
pprint(metadata)  # Pretty Print likewise
print(json.dumps(metadata, indent=4))  # Print metadata in JSON format

For xrdml file type

from materials.Xray.panalytical.xrdml import XRDML
import json
from pprint import pprint

process_file = XRDML("path/to/file")
metadata = process_file.extract()

print(metadata)
pprint(metadata)  # Pretty Print likewise
print(json.dumps(metadata, indent=4))  # Print metadata in JSON format

For dm4 file type

from materials.EM.dm.dm4 import DM4
import json
from pprint import pprint

process_file = DM4("path/to/file")
metadata = process_file.extract()

print(metadata)
pprint(metadata)  # Pretty Print likewise
print(json.dumps(metadata, indent=4))  # Print metadata in JSON format

For ibw file type

from materials.AFM.oxfordAFM.ibw import IBW
import json
from pprint import pprint

process_file = IBW("path/to/file")
metadata = process_file.extract()

print(metadata)
pprint(metadata)  # Pretty Print likewise
print(json.dumps(metadata, indent=4))  # Print metadata in JSON format
