Hello FSL experts,
I am using fslmeants with a probabilistic mask and I seem to extract the
same timecourse values regardless of if I include the --no_bin flag...
Additionally, these outputted timecouses are also identical to the output
when I use a binary version of the same probabilistic mask. That said, the
--no_bin does produce differences if I also include the --eig flag, though
I do not know if this would be an appropriate solution. My end goal is to
use the timecourses as regressors in resting state functional connectivity
analysis.
I am not certain why in the first case fslmeants seems to be applying a
default binarization of my probabilistic mask, but I am hopeful you may
have the answer.
Just for clarity, my understanding of the --no_bin is that this flag
should generate a representative timecourse by using the various
probability values of the mask to weight the contributions included in
generating the extracted signal (as oppose to the mean).
Please let me know if you would like me to include any additional
information.
Thank you for the help,
Jacob
