I have a question concerning group analysis in spm99. In the first step
of statistics, when I want to create the designmatrix it is very hard to
type all this data in. Is it possible to create the Designmatrix in an
matlab window by myself?
I loaded the mat-file of an existing Designmatrix, but I don't
understand the numbers in the array xX.X. I understood that the number
of rows is the number of pictures of my data, and that the columns are
the different conditions and sessions. Somehow the numbers seem to code
for the onsettimes of stimulation (negative ones for no stimulation and
positive ones for stimulation?), but what exactly do the floats code
for?
I hope you are able to help me,
sincerely yours,
anja schlack
