Dear SPMers
I have a question concerning the processing of images acquired with interlaced frames. Currently, I do not apply a slice timing correction in the preprocessing step since I use block designs with a TR of 3 sec. My question is where else do I have to take into account the interlacing in the preprocessing and statistical analysis steps? It seems to me that the spatial filtering of interlaced images should produce artifacts when the images are realigned for displaying and statistical analysis purposes.
The answer must be so obvious that I do not see it... Is there any default parameter to change?
Thanks in advance.
