I'm working with 99mTc-ECD SPECT data on SPM12 and would like to create a MNI-registered template from my own sample, since there are some debate against using the standard SPM2 SPECT template, which is based on 99mTcHMPAO brain perfusion images.
I've followed the procedure described in this paper (https://www.worldscientific.com/doi/pdf/10.4015/S1016237206000440), but I'm not sure which function I should use to average the previously normalized images to the standard template (e.g. coregister, realign or imcalc?).
Suggestions are highly appreciated!
Kind regards from Brazil,
Josie
