Hi FSLers,
When trying to run tbss_2_reg on a group of patients and controls I have using
either the -n or -t (one of the CONs as a target), FNIRT starts to work - I see
that via 'top'- but after a couple of minutes makes my MAC VERY heavy to use and
then just hangs. Looking into the FA folder, I see tbss_2_reg.e4733.1 all the
way through to my last CON and below is the message in each of these files..
Error occurred when preparing to fnirt
Exception thrown with message: FslSplines::Spline1D::Spline1D: knot-spacing has

I double checked my processing steps as per the FSL TBSS page and my FA images
open with fslview fine..
Any help is greatly appreciated.
Thanks,
Nader
