Issue Log:
Error: An empty value or a null value was detected in ["COLLECTION"]["COLLECTION_SUMMARY"]. A legitimate value should be provided for this required key.
Error: The value, "3299.5", in ["NM"]["OFFSET_FREQUENCY"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['ppm', 'Hz']. Ignore this when more complicated descriptions are required.
Error: The value, "3.893", in ["NM"]["ACQUISITION_TIME"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['s']. Ignore this when more complicated descriptions are required.
Error: The value, "12.0227 ppm, 8.417 Hz", in ["NM"]["SPECTRAL_WIDTH"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['ppm', 'Hz']. Ignore this when more complicated descriptions are required.
Error: The value, "0.04", in ["NM"]["BINNED_INCREMENT"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['ppm']. Ignore this when more complicated descriptions are required.
Error: Unknown or invalid sections, "CHROMATOGRAPHY", "Data".
Error: There must be either a "NMR_METABOLITE_DATA" section, a "NMR_BINNED_DATA" section or a "NMR_RESULTS_FILE" subsection in the "NM" section. Neither were found.
