RE: z-matrix plot/visualization
Hi Alfonso,
I was wondering if I could get some help with this matrix I'm trying to plot. I would like to organize the association matrix into modules. I've been looking online for a way to do this in MATLAB, but can't seem to have the necessary skills to do this with the ROI.mat file : /

Thank you in advance for any help and advice you may be able to provide.

All the best,

Fred

I was able to figure out how to plot two individual's z-matrix from the first-level results folder, one from each group using pcolor in MATLAB (attached). The code you provide (when used to plot a 1 -1 contrast or vice versa) is more what I was going for though!

Thanks again.

Hi Fred,

Not within CONN directly, but you could use some Matlab code like the example below to generate this sort of plots (e.g. when loading the data from a second-level results file)

load /data/conn_project/results/secondlevel/ANALYSIS_01/AllSubjects/rest/ROI.mat;
z = cat(1,ROI.h); % effect-sizes (typically fisher transformed values)
r = tanh(z);         % convert to r coefficients

figure
imagesc(r);
axis equal tight
colorbar

Let me know if this is what you had in mind

Best
Alfonso

Anybody out there know how I can plot the z-matrix in a format similar to the attached image?

Thank you so much!!
