Hello all,

After running the program dcm2niix_afni with this command : dcm2niix_afni *, I realized that the offset in slice acquisition time are set to 0 (3dinfo -slice_timing dset+tlrc). Is this really the case that the timing offset has been corrected? I don't see any info about that in the dcm2niix_afni documentation. Then, when I run 3dvolreg with the -tshift flag the program says the dataset has no time offset.

Also, I noticed that the dcm2niix_afni program keeps running and outputs many more datasets appending a, b, c, d...to the filename :
found 195 DICOM image(s)
