Dear all,
We have followed the reprocessing steps with T1 and T2 EPI images
according to the previous mail.
1) realign EPI dataset and just produce a mean image (don't reslice the
other images).
2) coregister T1 to mean of realigned EPI images.
3) normalize the T1.
4) apply the normalization parameters from the T1 to the EPI images.
5) now stats and T1 will be in normalized space.
The result from our fMRI experiment was far from expected especially for
the second step. T1 and the mean of realigned EPI images can't map exactly
together. Instead, only part of the mean of realigned images (8 slices for
one image file, 62 images) is mapped into T1 image. I doubt if it will
affect the following results. Could someone help me solve the problem in
order to continue the pre-processing?
Dorothy
