I have done the changes did you suggested:
mkanalysis-sess -analysis fc.rhipposeed.mni305 -mni305 -fwhm 6 -notask -taskreg R_Hippocampus.dat 1 -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -polyfit 5 -nskip 4 -mcextreg -fsd rest -TR 3 -per-run -hpf 0.01 -lpf 0.1 -force
but the error persists:
GLS Beta Pass
run 1 t= 0.0
Temporally filtering
GLS Residual Pass
run 1 t= 0.0
Temporally filtering
Error using chol
Matrix must be positive definite.
Error in fast_selxavg3b (line 947)
Wseg = inv(chol(toeplitz(acfrun))');
IMPORTANT
Please take in account that before to update the MacOs system to version 11, the command run on the same data independently, if I choose -hpf 0.01 -lpf 0.1 or viceversa.

You need to swap the values of the hpf and lpf. The way you have it, you are essentially filtering out everything above .01 Hz, which probably leaves almost no signal On 1/3/18 3:00 PM, stdp82@virgilio.it mailto:stdp82@virgilio.it wrote: > >mkanalysis-sess -analysis fc.lhamgseed.surf.lh -surface fsaverage lh -fwhm 6 -notask -taskreg L_Amygdala.dat 1 -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -polyfit 5 -nskip 4 -mcextreg -fsd rest -TR 3 -per-run -hpf 0.1 -lpf 0.01 Thanks > > > Il 31 dicembre 2017 alle 22.34 Douglas Greve <greve@nmr.mgh.harvard.edu> mailto:greve@nmr.mgh.harvard.edu ha scritto:What is your mkanalysis-sess command line?
