Your results are interesting. Can you verify you are displaying only one 
sample per two frames? That is, every other line. This is my issue.

Basically, trying to FFT full year of data at 1SPS. 24bit FFT len only 
does ~.53 years, so discarding every other sample will allow FFT of full 
data set.

I did notice that for very small files this works under windows as 
expected.

Will try the command line. Currently using the windows version, and use 
the GUI and wizard to import data.

Data files are currently CSV. Perhaps there is something there with the 
comma delimiter.

Will try to test more this evening.

Thanks,
Dan
