my_eddy_output.eddy_outlier_free_data.nii.gz
This is the original data given by --imain not corrected for susceptibility or EC-induced distortions or subject movement, but with outlier slices replaced by the Gaussian Process predictions. This file is generated for anyone who might want to use eddy for outlier correction but who want to use some other method to correct for distortions and movement. Though why anyone would want to do that is not clear to us.
