hello all,
i usually use Analyze files but am now using nifti format. When I do
pre-processing I ignore the first 3 volumes (6 seconds for a TR of 2)
and select from volume 4 onward from the virtually split nifti image.
I simply discarded them when using Analyze files, but I am unsure how
this works in nifti and virtually split files.
How does one account for this when defining condition onsets?:
If a condition started at the 4th scan collected, is the onset defined
at the 4th scan even if the first 3 volumes were discarded?
Or is the 4th scan now the 1st scan because I ignored the first 3 volumes ?
Thanks!
Michelle
