[Camino-users] Camino r1010 dtlutgen troubleshooting

[Irvin Teh]

Hi all,

Was wondering if anyone can help on an issue I've been facing while trying to migrate using camino from a Windows XP-Cygwin-camino_v2_880 setup I've been using previously, to a Red Hat Linux x86_64-camino_r1010 setup. Calculating the diffusion tensor and q-ball work fine, but I've been getting errors (See below) when trying to run dtlutgen. I've tried swapping between java versions jdk1.7.0 and jdk1.6.0_27, with no luck.

Would be very grateful if someone might know a fix for this, thanks!
