Hi Freesurfer experts,
I was wondering how many seeds we can use in fcseedcor command? I have more than 100 seeds and when I use all those seeds in the below command, I get this error:
Command: fcseedcor -s $subj -fsd rest -seed 1.dat -seed 2.dat -xreg global.waveform.dat 1 -xreg vcsf_mean.dat 1 -xreg wm_mean.dat 1 -xreg mcprextreg 6 -hpf .01 -lpf 0 -nskip 0 -sim 1000 -o cor_all.dat
Error: Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 1.768795e-22.
