Dear all,
I have a question about doing slice timing in SPM.
After reading some articles and the SPM manual, I realize that doing slice timing correction in fMRI data can make all the slices of an image be corrected in a same time point.
In my case, for example, I have 400 images of a subject in one experiment which is using event-related design module, and TR = 3 s.
That is, the whole information in those 400 images pass through 1200 seconds.
If I perform slice timing correction as my pre-processing before doing other spatial processing, do I have only 400 time points information as the output results? (Because there are 400 output images after doing slice timing)
If I need all the information through an experiment (1200 seconds), should I interpolate the slice timing correction results (400 images) to 1200 images?
Moreover, I would like to know that if the number of the images is large as my case, should I perform slice timing as the pre-processing?
Best Regards,
Debbie
