I have some data gathering with the multi-band/Ts=2s(the filed_mapping_BOLD folder having  50 items), when I use the DPARSFA software for preprocessing, I was told not to do the "slice timing "step, but others said that I should do the "slice timing" in other software, and the data must be "slice timing". I was confused by those opposite view, what should I do then ? Can I use the data processing by the DPARSFA without "slice timing" to do the analyze?

Many thanks!
