Local DTI extraction results don't match the values given in the tutorial

SCT

Hey Joshua,

I’m wondering if ANTs is working because I’m getting differing data from my DTI extraction than what’s posted for the tutorial and I’m wondering if its related to motion correction or some other issue. I attached the data and QC.

Dear @sabaig,

Thank you for pointing out this discrepancy to us.

  • It may be possible that the values in the documentation are out of date (due to changes in the processing pipeline). The values displayed in the documentation are uploaded manually, and so it may be that we forgot to update the values.
  • Or, as you suggest, there may be some issue/error with your local installation (less likely).

I will do some testing to see if I can reproduce the discrepancy on my local machine and report back shortly.

Kind regards,
Joshua

On my Linux laptop, I was able to produce values identical to the ones you produced. So, I believe that there are no issues with your installation of SCT.

I will look more deeply into updating the documentation to avoid confusion in the future. My apologies for the confusion, and thank you again for catching this mistake.

Kindly,
Joshua
