Hi Anastasia,
The error message occurs for other control points too, but it does not kill the -prior stage.
I have attached the full trac-all.log file.
This error message is also found in other subjects where I am struggling to get a good initialisation.
The ERROR: fio_pushd:subject/dmri/xfms/cvs/final_CVSmorph_tocvs_avg35/mri
Thank you!
Best Wishes, Elijah
