Hi,
an additional observation:
I had two data sets with 256x256x15 image size, 70 and 90 volumes,
respectively. None of them made it to a successful FEAT analysis. On
the other hand, I tried another data with 128x128x16 image size, 124
volumes and I got success. So, there is certainly something related
to file size but it is not disk space or quota. Does this program
have any memory, file size or array/pointer size limitations (in the
Linux distribution)?
Thanks again,
Tugan
