I'll wish to make an ICA analysis on my resting-state data.

In fact, I have already preprocessed my data with AFNI (timing and motion correction, and regression of non-interest parameters). Then, I concatenated all sessions by subject, so I have one file per subject (which I converted in NIFTI file).

When I ran ICA with MELODIC program I had an error message and the program abort after Prestats step.

This is my error message:

    (file "/usr/local/fsl/bin/feat" line 119)

I would be very, very grateful if someone could help me!
