Hi AFNI team,

I am using resting state data from a database. I noticed that for some of the participants the TRs in the dicom and nifti headers do not match. To pull this information I used the dicom_hdr command ('ACQ Repetition Time' field) and 3dinfo -tr. Do you know why this might occur? Should I change the information in the nifti header to match the dicom information?

Thanks,
Jenna
