Questions regarding two fMRI datasets with different TR

[shrimpj]

Dear neuroCombat expert,

I have three fMRI datasets preprocessed with fMRIprep having different volumes due to different TR: 1) 91x109x91x192 (TR=2510, slice thickness=2.51); 2) 91x109x91x570 (TR= 720, slice thickness=0.75); 3) 91X109X91X240 (TR=2000, slice thickness=2). When I convert the 4D image to a vector I have different vector lengths. Given neuroCombat requires the same vector length, I wonder how can I resclice/resample the data to have the same vector length. Any suggestions are appriciated!

Best wishes
Joyce
