Reproduce RF plot

1

Dear MRtrix Developers Team,

I hope this message finds you well. I am reaching out to inquire about the possibility of reproducing a plot similar to those presented in the Dhollandar paper @ThijsDhollander (reference included below).

plot

I have already calculated all the response functions for my dataset, which includes 2 b0, b750, b1500, and b3000 images. Specifically, I would like to reproduce a plot for a sample that includes ST, MSMT, and SS3T, similar to the example provided in the paper.

Could you please provide any advice or detailed steps on how to achieve this? Your assistance would be greatly appreciated.

Thank you for your time!

Kind Regards,

Ibrahim

Hi @ihattan,

If I understand correctly, all you need to plot are the values in the first column of each response function file. These plots can’t be produced within MRtrix directly, but you can use any number of software packages to do this, including Matlab, octave, python + matplotlib, Excel, gnuplot, R, and many others too.

For example, using octave (Matlab-compatible and free):

load wm.txt
load gm.txt
load csf.txt
bvals = [ 0 1000 2000 3000 ]
plot (bvals, [ wm(:,1) gm csf ], 'linewidth', 2)
legend ({ 'wm', 'gm', 'csf' })

I hope this helps.
All the best,

Donald.
