Hello FSL Experts,

I have acquired DTI data with 120 directions, 1.3 mm resolution and b value 1000. I put the seed in the Primary motor cortex and ran Probtractx but I get bad_alloc error. I got stuck and have no idea how to proceed.

We have 8 GB RAM, 1GB Graphic card and 2 TB of hard drive on our system which I think, would be enough to process 120 directions.

Any suggestion or comments to overcome bad_alloc error message would be highly appreciated.

I hope to hear from you soon.

Cheers,

Wu
