Hi Doug
Thank you very much for your reply.
I am doing these analysis in each subject’s self space, and my ROI is a
handmade cortical label in ascci format.
In this case, would the indices be the vertex Id in the label file?
also, instead of f=MRIread('f.nii.gz’); can I use “sig.nii.gz” to get
Do you mean all the voxels separately? I don't think I have anything,
but you can do it in matlab with something like
seg = MRIread('seg.nii.gz');
indices= find(seg.vol == IndexOfYourROI);
f = MRIread('f.nii.gz');
fmat = fast_vol2mat(f);
froi = fmat(:,indices);
this assumes taht f.nii.gz and
Hi all
Is there any command for extracting the fmri activation from all voxels in an
ROI?
I know I can use funcroi-config, funcroi-sess and funcroi-table-sess to extract
the average activation in a specific ROI from a specific contrast. But what if
I want to extract the values of each voxel
