Summary of what happened:
I am trying to use fmriprep to process my bold data with slice timing correction.
I downloaded some public fmri dataset that don’t have SliceTime in the JSON side card. I emailed the author of the dataset and they told me the order is like interleaved (1, 4, 7, 10, 2, 5, 8, 3, 6, 9). I know i can manually calculate the slice time by doing (1, 4, 7, 10, 2, 5, 8, 3, 6, 9) * TR/num_slices. In such case the TR is 3 and the num_slice is 45. I am wondering if it is possible to use the slice order instead of the exact slice time? (According to bids documentation, it seems that TR have to be time in seconds, not order) I am worry that the actual slice time is slightly smaller than the one I calculated with TR. What else could i do to ensure slice timing correction is done properly? given the TR is 3 seconds for this dataset, which is not small, i don’t feel i can just ignore slice timing correction. Does anyone have any suggestions besides using the manually calculated SliceTime so fmriprep can do slice timing correction fo me?
