Hello, we seem to be experiencing a minor problem with spm_jobman with
all versions of spm5.
the 'jobs' struct has two fields:
jobs{1}.stats{1}.fmri_spec.sess.multi and
jobs{1}.stats{1}.fmri_spec.sess.multi_reg which I believe are supposed
to hold location of files which contain the covariates of interest and
nuisance regressors respectively. However the resulting SPM structure
has all of the regressors specified by the files indicated in both
fields as covariates of interest in SPM.xX.iC, and no regressors are
listed in SPM.xX.iG, as I think they should be. So I have two questions:
1) Am I specifying the nuisance regressors incorrectly? If so, what is
the proper way to specify them?
2) My understanding is that the non-sphericity of the noise is computed
only in the voxels which pass a F-test for the covariates of interest,
so would this bug/error result in a small mischaracterization of the noise?
