Dear SPM authors,
I have encountered what appears to be a bug in the "specify design"
component of the fMRI module. After determining the onsets of a given
condition (in the "variable SOAs" path) one is then asked to
specify the durations of each occurrence of that condition (in the
"variable durations" path). But, several steps later one is
asked to specify a (single) duration for each condition, apparently
in ignorance of the fact that one has specified a vector of such
durations for each condition previously. Moreover, what one enters at this
point seems to override the vector of durations entered first. So, it seems
that one cannot incorporate variable epoch durations into the design matrix.
Am I missing something or is this a bug?
Many thanks,
Eric
