A command to replace 3dfim+

Hi experts,

I am using 3dfim+ to calculate the correlations fMRI time series. I always got the warning as bellow. But I didn’t find a new command to do the same thing. Could you please give some advice?

*+ WARNING: This program (3dfim+) is very old, may not be useful, and will not be maintained.
Program to calculate the cross-correlation of an ideal reference waveform
with the measured FMRI time series for each voxel.

Thank you!


3dTcorr1D computes the correlation of a 1D time series with a 3D+time dataset.
