Hi, This is the expected behaviour, as resampling the filtered_func_data can lead to enormous files. However, if you want to do it then it is easily done with the applywarp command. Just do: cd blah/blah.feat applywarp -i filtered_func_data -r reg/standard -w reg/example_func2standard_warp -o filtered_func_data_std That should do what you want. All the best, Mark On 12 Jun 2017, at 10:53, Maarten Mennes <[log in to unmask]<mailto:[log in to unmask]>> wrote: Hello, I'm running into the weird problem that featregapply skips filtered_func_data.nii.gz. It happy applies the registration to the present example_func, mean, and mask file, but does not do it for filtered_func_data. Any ideas?
