Hi all:
I tried to use slice timing in spm99 for some fMRI data. I expected slice
timing in spm99b and spm99 to be similar, but they are not! In spm99,
inputs of TR and TA are required, but NOT in spm99b. The version in
spm99b is v2.3 and ,in spm99, v2.6.
(An earlier post about TA was found in the archive in Sept 99, but
generated only one response/follow-up question.)
My questions:
1. What is the acquistion time (TA)? Can someone give an example how
this is determined?
2. I used spm99b's slice timing for many previous sets of data. Were
those outputs correct even though TR and TA were not prompted for input?
