Import data from *.ch file

Hello - has anyone ever tried to import gas chromatograph data from files with .ch extension?

I am not really in that business but just in case it would help :

Chromatographic File Converter • chromConverter (ethanbass.github.io)

I downloaded the chemstation_130.ch file from the chromConverter repository and it looks like it's possible to extract the data using fread:

file_name = 'chemstation_130.ch';

fid = fopen(file_name);
  data = fread(fid);
fclose(fid)

figure
area(data,'EdgeColor','none')
xlim([0 500])

However, while it appears to be a GC spectrum, this method doesn't provide any metadata so I can't be sure what the units are. @Davide Masiello, you might try opening your own files using fread to see if the data match what you would expect.
