Plot Gannet Spectra from matlab output file

MRS Software Gannet
1

Hello!

Currently I have Gannet running smoothly.

I am saving the matlab output file
When I load it, I have one structure (let’s call it MRS)
In that structure, there is:

Where would I find the final output spectra, so that I could create something like this:

Oh I’m getting somewhere:

plot(real(MRS.spec.vox1.GABAGlx.diff))

If this is what I should be doing, my next questions would be:

How do I get this in ppm?
Do I use .diff or _scaled.diff? Or something else…

MRS_struct.spec.freq :slight_smile: Output structure attributes (markmikkelsen.github.io)

5

Oh yes! That helps me get the ppm!

but do I use .diff or _scaled.diff? Or something else?

For anyone else who might stumble on this in the future:

plot(MRS.spec.freq,real(MRS.spec.vox1.GABAGlx.diff_scaled))
set(gca, 'XDir','reverse')

produces:

Hi @weberam2,

The PaperPlot.m function in Gannet is a wrapper function allowing you to plot the spectral results at publication-level quality. Just type help PaperPlot for full usage instructions.
