Hello.
I wanted to create a time series data for a selected set of voxels.
I have the PRI coordinates for a list of the voxels I am interested at, and a time series data vector for each one of those voxels.
How can I create a BRIK file to be loaded as an overlay in AFNI, that will contain the time series data of the voxels I have in my list?

I saw that there is a function for writing brik files ( [err, ErrMessage, InfoNewTSOut] = WriteBrik (Vnew, InfoNewTSOut, OptTSOut);) but it is not clear to me how the voxels specification is done... i.e. the matching between time series vector v to it's voxel [x=i,y=j,z=k] ?

Thanks
