Hi Alfonso,

That's helpful. I used both ART parameters and the 'detrending' and 'despiking' options. I'll try to vary this once I get the analyses running again. Unfortunately, I keep running into the same error during the preprocessing stage, and am not sure why:

ERROR DESCRIPTION:

Reference to non-existent field 'Y'.
Error in ==> conn at 1669
if isfield(CONN_h.menus.m_preproc.Y,'issurface')&&CONN_h.menus.m_preproc.Y.issurface
Error in ==> conn at 1585
conn gui_preproc;
Error in ==> conn_menumanager at 103
feval(MM.MENU{n0}.callback{n1}{1},MM.MENU{n0}.callback{n1}{2:end});
CONN v.14.f
SPM8 + Beamforming DEM FieldMap MEEGtools marsbar
Matlab v.2010b

Do you know what I did wrong, Alfonso? I've used the same files and locations as before, only this time I started a new project instead of loading the old one up...

Thanks,
Merina
