Hi Anastasia,
Thank you for clarifying that. I have a follow up question.
To avoid this error while running the ball and stick model fit( Syntax error:
"(" unexpected), I ran it locally using "bedpostx $path_to_dmri".
The results of the overall path statistics differ from those in the tutorial.
I've attached my results for the left ILF (pathstats.overall_redone.txt) and
the tutorial results (pathstats.overall_original.txt)
Is this difference due to running them on different machines or is because I
had to run the bedpostx command directly ?
Thanks!
-Prad

Hi Prad - What will affect the speed is whether you run it locally on your
computer (in which case it'll process one slice after the other) or on a
cluster (in which case all the slices will be processed in parallel on
different nodes of the cluster). This is the case regardless of the
version that you use.
Best,
a.y
