So, the cdf files generated by the Agilent software must be converted to the new cdf file structure before they can be opened as hdf5 files. The same problem will be encountered by others trying to read the Agilent generated cdf files as hdf5 format, using other languages and toolkits – e.g. Hdf5 files can be opened in LabVIEW using the excellent h5labview toolkit, whereas the old 2.3.2 version netCDF files cannot. The benefit of the newer versions of NetCDF files is that they are written in hdf5 format. This version predates 1994! The current version (as I write) is 4.5.0. The Agilent netCDF files ( AIA/ANDI files are a special form of netCDF files) are written in a practically antediluvian NetCDF version – 2.3.2. Update the Agilent generated CDF files to a newer version d files (well, folders actually) and choose those that you want to convert to AIA format. Then, choose a folder containing the Agilent. This is a common format used to move GC-MS data between different software regimes.

The Agilent software can batch convert the Agilent format data to ANDI/AIA/ NetCDF interchange format. Step 1:Ĭonvert GC-MS data files to ANDI/AIA/NetCDF interchange format I could describe all the different routes I tried, but I suspect that just giving the method I have found that works best will be more useful for people who, like me, just want to be able to pull GCMS data from CDF files. The aim was to reduce some of the burden on the technicians who were having to format the reports by hand – extremely dull and time consuming.

I was trying to write a tool that we could use to batch process GC-MS data from a teaching laboratory to present grouped reports to the students, in a format that matched a similar output from the GC-FID systems we also have. After spending a few days writing a tool to read GC-MS data files into LabVIEW, I thought I’d publish what I found – so others do not have to repeat my mistakes! The steps I describe here will also be useful to people who are using languages other than LabVIEW’s G to understand how to get GC-MS data from netCDF files.
