Hi,

I have preprocessed fMRI data and have realized when trying to run 3ddeconvolve that the header information in my fMRI data is incorrect. The data have a TR of 2s but the header information say 1s. I checked and the data had a 1s TR in their header from when I converted them from DICOM to nifti using MRIconvert.

I am wondering how do I change this? Is it ok to change this in the processed data and continue with 3ddeconvolve now or should they be reprocessed from the beginning?



Thanks.
