Hi all,

When trying to apply DARTEL deformations to a coregistered image in SPM12 using the ‘Deformations’ batch module with a ‘Composition’ that includes a DARTEL flow, I get:

Failed  'Deformations'

Cell contents reference from a non-cell array object.

In file "/apps/spm/spm12b/spm_deformations.m" (v5506), function "get_dartel" at line 205.

In file "/apps/spm/spm12b/spm_deformations.m" (v5506), function "get_job" at line 80.

In file "/apps/spm/spm12b/spm_deformations.m" (v5506), function "get_comp" at line 48.

In file "/apps/spm/spm12b/spm_deformations.m" (v5506), function "spm_deformations" at line 17.

This persists when when all other Deformation fields are removed from the ‘Composition’. Is this a bug?

When I use SPM8 for this it runs OK but I  does not yield sensible normalised (w*)  images - my test coregistered image has an obvious rotation which isn’t corrected . I’ve included in the Composition the y_* Deformation field and the u_* DARTEL flow. Changing their order and changing between backward and forward for the flow doesn’t help. Can anyone help?
