HI! I need to subsample my original 4D .nii files (the f.nii or the fmc.nii after motion correction) from 2.5 2.5 2.75 to 2 2 2 mm, in each orignial 4D nii are 200 volumes: After subsampling with mri_convert -vs 2 2 2 001/fmc.nii 001/fmc.nii -oi -ii
the output info tells me that the inputstructure changed from nframe 200 to nframe 1 (in outputstructure)
as a consequence my subsequent analysis of the estimation of the statistics (-selxavg3-sess, not important I guess) cannot be performed.
if I do the same for the f.nii files, the same happens, and -preproc-sess enters with an ERROR ('cannot perform mc')
How can I keep my 200 frames in the 4D nii and subsample my voxels at the same time, to then continue my statistics?
I would be extremely greatful I someone can help!
