[Camino-users] Error converting large DWI file

[Elizabeth Zakszewski]

Hello,

I have a DWI .nii file that is 3.4G.  I had to increase the Java heap size
in niftidt2camino to 50G in order to get it to run (our server should be
able to handle 96G). But the conversion still terminates with the following
error:

NIFTI to CAMINO, this wil convert the data from scanner order to voxel order

We have never seen a Negative seek offset error before and aren't sure how
to troubleshoot. Is there a way to correct this, or a better way to convert
a large file?

Thanks,
Liz
