Hi,
I've come across a FEAT GUI registration warning at the fnirt command stage in the FEAT Report Log. Could someone please help me interpret the warning, so I can see if I need to alter something? The registration results look reasonable, but if the warning suggests there is room for improvement, I'd like to know how to go about it. I've copied the fnirt command and its warning from the FEAT Report Log:
/usr/local/fsl419//bin/fnirt --in=highres_head --aff=highres2standard.mat --cout=highres2standard_warp --iout=highres2standard --jout=highres2standard_jac --config=T1_2_MNI152_2mm --ref=standard_head --refmask=standard_mask --warpres=10,10,10

Any help regarding what the tolerance requested and achieved mean would be greatly appreciated.
