Hi,
I'm using 3dfim+ to correlate the timeseries from one voxel with the rest of the brain as follows:
3dfim+ -out Correlation -bucket Corr_w_FG1 -ideal_file 019_047_003.1D -input RivFH_F+orig
where the *.1D file contains temporal data from one voxel (as may values as the number of subbricks in the -input dataset).
When I run this I get the following error message:
3dfim+ Error: Improper X matrix (cannot invert X'X)
What am I doing wrong?
I haven't used 3dfim+ before, so pardon the ignorance.
:)
