Current and Future Functionality
SpecDAL can read file formats from ASD, Spectra Vista, and Spectral Evolution spectrometers. We hope to soon have drivers for Ocean Optics, UniSpec, and Piccolo spectrometers. Current functionality includes filtering, jump correction and splicing, overlap blending, and resampling.
We hope to add the following functionality:
- grow the list of supported file formats
- create command line utility programs for the most common processing tasks
- create example workflow scripts to encourage consistent processing
- create a class model that supports the internal storage of wavelength, radiance, and other transformation models
- develop a model transformation class to allow statistical models (e.g. plant chemistry) to be stored internally and applied in real time
- develop functionality to seamlessly translate files between supported formats
- begin development of Spectral Information System software with a comprehensive GUI for data visualization, analysis, and processing
- create a non-proprietary open file format standard that allows data from different instruments to be directly exchanged and compared
- create language bindings for other languages like R, Java, Ruby, C++
Examples
We've written a few "pipeline" scripts to suit our needs. We'll get these into the Github repo soon. Usage of pipeline scripts looks like this:
usage: pipeline_ASD_processing.py [-h] --input_directory INPUT_DIRECTORY
[--subset_wavelength_range SUBSET_WAVELENGTH_RANGE SUBSET_WAVELENGTH_RANGE]
[--jumpcorrection_wavelengths JUMPCORRECTION_WAVELENGTHS JUMPCORRECTION_WAVELENGTHS]
[--jumpcorrection_stablezone JUMPCORRECTION_STABLEZONE]
--grouping_output_name
GROUPING_OUTPUT_NAME --grouping_pattern
GROUPING_PATTERN [--recursive]
optional arguments:
-h, --help show this help message and exit
--input_directory INPUT_DIRECTORY
--subset_wavelength_range SUBSET_WAVELENGTH_RANGE SUBSET_WAVELENGTH_RANGE
--jumpcorrection_wavelengths JUMPCORRECTION_WAVELENGTHS JUMPCORRECTION_WAVELENGTHS
--jumpcorrection_stablezone JUMPCORRECTION_STABLEZONE
--grouping_output_name GROUPING_OUTPUT_NAME
--grouping_pattern GROUPING_PATTERN
e.g. *-X OR *_X for leaf level averaging
--recursive
