CDF to TXT Converter

Python script that reads GC-MS or LC-MS data stored in the ANDI/AIA NetCDF (.CDF) open interchange format and exports each file as a tab-separated plain text file. The output includes global metadata, instrument information, a Total Ion Chromatogram (TIC) table, and the full mass spectral data with scan number, retention time, m/z, and intensity columns. Handles the ragged-array layout used by the ANDI/AIA standard (flat mass_values/intensity_values arrays indexed by scan_index and point_count). Supports batch conversion of entire directories. Only requires scipy as a dependency.
