Dear SPMers,
I analyse event-related data in fmri with SPM5.
I can't run a modele 1rst level when I introduce a parameter
in "parametric modulation"(the response of subjects) for 4 of my 8
conditions.
- a problem for only 2 subjects but OK for 16 subjects !!The parameters
values are though similar to the others subjects.
- all is right when I put paramaters in the first session only (or not at
all).
Error message is:
"Assignment has fewer non-singleton rhs dimensions than non-singleton
dimensions subscripts."
I don't understand what it means!
Thanks in advance for any explanation or suggestion !
GR
