Hello SPM users,
I am new at SPM and am having some difficulties designing a matrix for a
slightly unusual blocked analysis. Because of the nature of the
experiment, there exist 5 distinct blocks presented for 120 scans each for
a total length of 600 scans (TR = 4 sec). I'm using the HRF function and
no temporal derivitavies, parametric modulation, nor variable SOA.
Following the procedure described online, I inputed the epoch length for
each condition only to get the error described at the bottom of this
message.
I tried modifying the analysis to take several repeating epochs rather
than to use 1 large epoch per oondition, but to no avail.
Any information you might be able to provide could be very useful. Thank
you.
