Hello,
I have two short questions about the fslmeants function.
1. what exactly does the --no_bin flag do? I am using a probabilistic
atlas for my mask, and I was wondering if the no_bin option would give
an eigenvariate that was somehow weighted by the probabilities within
the mask.
2. I am also extracting a mean timeseries from the res4d files and am
working outside of the GUI. My understanding (from the featquery log
files) is that to extract a weighted time series you:
1. normalize the probabilistic mask by dividing by its mean
2. multiply 4d data by the mask
3. use flsmeants -i multiplied_4d_data -o output -mask normalized_mask
I noticed in featquery when you put in a probabilistic mask and allow
featquery to binarize it, featquery first thresholds at .5. I was
wondering if fslmeants does the same thing here (i.e., only extracts
from voxels in the mask with p>.5) If so, is there a way I can turn this
off?
Thank you very much for the help,
Ian
