Note- the above image is a LabVIEW snippet вЂ“ just click-and-drag it into a LabVIEW block diagram. The вЂњ -uвЂќ command is telling nccopy to convert unlimited dimensions to a fixed size in the output file.ДЄ simple LabVIEW wrapper for nccopy can be written like this:

#AGILENT CHEMSTATION CHANGE DATA FILE PATH UPDATE#

The вЂњ -k 3вЂќ command is telling nccopy to update the output file to the new version.

This can be useful if you just want to quickly look at a file and the information is contains. ncdump.exe is a small program that will take a netcdf file and dump its contents into a text file so it can be read by a human. There are two tools in here of particular note вЂ“ IвЂ™ve highlighted them above. In the netcdf folder (probably in your Program Files), you will find a subfolder called вЂњbinвЂќ:

#AGILENT CHEMSTATION CHANGE DATA FILE PATH INSTALL#

Install the netCDF4 version suitable for your system вЂ“ I installed the 64bit version without DAP. I was working on a Windows system вЂ“ you can download an prebuilt version netCDF for Windows from here. To undertake this conversion, first you need to install netCDF.

In fact, it was Martijn Jasperse, the author of the h5labview toolkit, who recommended this step and how to do it. 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 вЂ“ 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 netCDFВ files ( AIA/ANDI files are a special form of netCDF files) are written in a practically antediluvian NetCDF version вЂ“ 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:Д¬onvert 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 вЂ“ 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 IвЂ™d publish what I found вЂ“ 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 LabVIEWвЂ™s G to understand how to get GC-MS data from netCDF files.
