I have a question about setting up design matrix for block length that is
not a dividable by TR.
I found out in older messages that one can set non-integer scan
numbers/onset time in SPM5.
I tried to use the onset time for my block.
onset: [5.05 25.03 45.8 .....]
and it turns out that my design matrix looks like this ( .jpg in attachment )
I couldn't figure out why it is the case.
This is just a 6-block block design, starting with a off-condition.
