Dear SPMers:
when doing the slice timing correction,
I am puzzled with the following setting:
Acquisition order?(1=first slice image)
interscan interval(TR)=2s
Acquisition Time(TA)=1.9167s;
My questions are:
one, How can I know the slice acquisition order ? Is it from the FMRI
scanner setup?
two, does the position number of a slice within the image file always
ascend along Z axis's direction? i.e. from-toe-to-head direction
three, what is the relationship between the interscan interval and
acquisition time?
A example is better.
thank you very much!
