Would you mind attaching screenshots of both situations? It would help immensely in this situation, I should think. This is because, at first glance, using Nifti files from different programs should *not* produce different results. Perhaps the steps you went through were vastly different.

Subject: [SPM] Different Results with Imported DICOM vs NIFTI
SPM,
I was recently checking some data by comparing a 1st level contrast on an image from a 4D NIFTI file that was created by our scanner to an SPM-converted NIFTI, from the scanner's DICOMs, of the same contrast (processed the same way). This was done in SPM12b. In the DICOM import step, I did receive the message that the algorithm had to guess to construct the NIFTI. Nonetheless, the contrast image produced for each format is different (some activations in one are absent in another, and some activations occur in different places, resembling a coregistration error).
What might account for these differences?
Best,
Drew
