Dear Mark,
Thank you very much for your kind information. I resampled the image and it worked.
Thanks again,

Hi,
This image is really very large and so I suspect that it may be
struggling
internally in invwarp to allocate room - although even if it did it
would
take a *long* time to generate the inverse. If you did resample your
image (say using ApplyXFM) to a lower resolution (either 1mm or 2mm
voxel size) then I think that should solve your problem.
All the best,
Mark
