Improving... now selxavg-sess finishes without error, and even mkcontrast-sess and stxgrinder-sess seem to work (see below for command lines). The output seems to be in .nii format though, which is something of a problem for the rest of our custom analysis stream (our matlab routines can only read

This means that the design matrix is ill-conditioned. This can happen if your using an FIR model (ie, not using -gammafit) and the stimuli are presented with some fixed timing with respect to each other with the elapsed time between them being less than the FIR time window. For example, if you pr
