Hello,

I'm trying to run 3dDFT on a surface and wondering why 3dDFT is changing DFT length. The data includes 112 time points - (4: stimuli + 10: resting) * 8 cycles.

Here is my script file and output:
3dDFT -prefix sample.DFT pb06.TMSfMRI.subj1_lh.lh.r01.detrend.niml.dset
++ Authored by: Kevin Murphy & Zhark the Transformer
++ Data length = 112 ; FFT length = 120
++ Output complex-valued dataset: ./sample.DFT.niml.dset

Thanks!
Taek
