Hi Laeticia,
Thank you for using Braph and I hope that it proves to be a valuable tool in your research.
When you save the results from Braph, they are saved in .fga files (for fMRI analysis) which you can load in Matlab. When the file is loaded, you will see a ga variable in the workspace which holds all the information you need.
In order to extract a measure you could do the following:
load(‘trial.fga’,’-mat’)
[ms_gr1,mi_gr1] = ga.getMeasures(measurenumber,group1);
% get only the values of the measure at the given density
value_gr1 = ms_gr1{density}.getProp(fMRIMeasureBUD.VALUES1);
In these lines, measurenumber is the number of the measure in the list that comes up when you type Graph.NAME on the command line. group1 is the number of the group in the cohort, density is the density at which you would like to extract the results.
Hope this helps. If you need something specific, please let me know and I can try to prepare a code that can do that task.
Best,
Mite
