Hello,
"melodic --help" did display the help info on melodic - so it did run.
However, I got "segmentation fault" error while running the feeds data
using melodic. The only thing I can find in the output folder in the
mask image, and that one seems fine (compared to the mask image in the
corresponding ica folder in results folder). So I am guessing that
something happened during compilation? (there were no errors reported).
any ideas? Thanks!!
here is the output from running melodic:
melodic -i feeds/data/fmri -v --report
Melodic Version 2.0
Melodic results will be in feeds/data/fmri.ica+
