Gang,

Could you check my steps and tell me if I did everything correctly? Im pretty sure I did these steps correctly but it never hurts to have the Gurus blessing right?


Step 1.

Following 3dDeconvolve I sub-bricked the Beta/Coef file from the bucket file

3dbucket -prefix s1_condition1+orig -fbuc s1_run3_bucket+orig'[10]'


After reading around a bit Ive since discovered that I dont need to sub-brick the beta files from the bucket file.

Step 2.

My next step I deviated from the norm a little bit, instead of running the Group analysis I warped the file to Talairach space. I did this because in the past when we warped mean group data it always looked funny. Is that ok?

adwarp -apar s1-spgr+tlrc -dpar s1_condition1+orig


Step 3.

Here is the significantly shorter version of my 3dAnova2 script.

3dANOVA2 -type 3 -alevels 2 -blevels2 \
-dset 1 1 s1_condition1+tlrc \
-dset 2 1 s1_condition2+tlrc \
-dset 1 2 s5_condition1+tlrc \
-dset 2 2 s5_condition2+tlrc \
-voxel 2000 \
-fa Fstat_all \
-amean 1 mean_memboth_fa \
-amean 2 mean_memboth_ff \
-acontr 1 -1 0 0 1vs2 \
-acontr -1 1 0 0 2vs1 \
-fa Fstat_mean


Thank you so much for your help, I really appreciate it!
