Warning message during registration process (solved 9/8/20)

Submitted by rku on Wed, 09/02/2020 - 16:26

Update on 9/8/20:

It turned out that the registration setting was not correctly loaded though the path of the dmc file was assigned in GUI and placed in diff_prep_work folder. Once the parameters were manually entered in the advanced registration options, the registration processing did not return any warning messages.



Modified mec files

I have a few questions about the mec files for DIFF PREP.

I am using DIFF PREP on ex-vivo specimens that are not expected to move during the scan.
Is it possible to create a mec file that corrects only for eddy currents but not motion?

In the mec file, there are optimization and bracketing epsilons.
How are these epsilons used during the optimization process?

Using T1 structural data

Submitted by smeisler on Sat, 04/11/2020 - 16:25


I would like to use TORTOISE on a data set for which T1, and not T2, structural data were collected. I read about a work-around for using T1 images here which seems to involve attenuating non-brain regions. Apparently this suggestion came from a TORTOISE developer. I just want to make sure that this would be valid and/or necessary to do in the most recent version of TORTOISE (3.2.0 at time of writing).
