Hi,
I have three identical dti runs per subject, each with 70 timepoints (10b0
and 60 grad directions) resulting in 210 timepoints per subject.
Suppose that in one run I have 2-3 timepoints in which some slices are
affected by artifacts (spikes, noise - see attached example). What is the
best way to proceed?
1. Discard that run ending up with some subjects having 2 runs and some
subjects having 3 runs.
2. Replace the artifact timepoint with the average of the same timepoint
from the other two runs.
3. Discard the whole subject data alltogether.
Thanks,
Alina
