Hi Natasha,
FSLview is automatically trying to run in “FEAT” mode and load in the filtered_func_data ( which doesn’t exist yet as the run has failed! ) can you copy the prefiltered_func_data_st and mask images to another directory and view them there?
Kind Regards
Matthew

If you can find the file prefiltered_func_data_thresh.nii.gz in your directory then do "cd" into that directory and re-run the command. If you don't have that file then it makes it harder to track down, so let us know if that's the case or not.
