Dear Anderson,
Thank you for your quick answer!
when applying fsl_glm slice by slice, there occurs an error in slices with a low number of brain voxels as in brain stem slices or slices near the vertex. Anywhere else in the brain it works very well.
This is the error message:
Image Exception : #4 :: Incompatible number of mask positions and matrix columns
terminate called after throwing an instance of 'RBD_COMMON::BaseException'
Aborted (core dumped)
this is the link for an example slice in the brain stem, the csf mean TC (to be regressed) and the used fsl_glm command line:

Any idea why this happens and how it can be fixed?
Cheers,
Jessica
