I think you should specify -s and another threshold. If there are not outliers over this threshold, then nothing will be produce. I suggest you change the threshold and try the option -s to see whether your results make sense

Betreff: [FSL] No result file from fsl_motion_outliers


I am running fsl_motion_outliers using the instructions in

The input file that I give is a 4D nii of the mni motion residuals, and the command seems to be running (no error is produced).
However, no result file is generated in the designated result file path.

The command that I used was:

fsl_motion_outliers -i <full path my input 4d nii with no suffix> -o <full path of my output file no suffix>  --fd --thresh=0.5

Any advice would be highly appreciated.

Many thanks
