OMNIC to CSV

This script converts OMNIC files to CSV files.

Installation

Install spectrochempy and pandas into a virtual environment.

pip install spectrochempy pandas

For your convenience, the environment.yml file is provided for creating a conda environment.

conda env create -f environment.yml

Getting Started

In OMNIC, export the data as .spa files by selecting the desired data and clicking Series > Split Series File > Ok.

Make sure you save this collection of .spa files in a directory indicating the series name.

<series_name>
    <series_name>0000.spa
    <series_name>0001.spa
    <series_name>0002.spa
    ...

Usage

The omnic_to_csv.py script takes a directory of OMNIC .spa collections and converts them to CSV files corresponding to the collection names.

python omnic_to_csv.py <input_dir> <output_dir>

Example

python omnic_to_csv.py data csv_files

CSV Files

In the CSV file, the first column is the UNIX timestamp. Subsequent column headers indicate the wavenumber. Each row corresponds to the temperature at the given timestamp and wavenumber.
