Hi,
I am using a T1 anatomical volume with identical slice prescription than my
epi-volumes to register T1 first to 3d high res volume and then to standard
brain and then apply the transformations directly to the epi-data. Since I
want to use the original (no BET) T1 and 3d volumes in the first step (low
res > high res) and a skull stripped 3d volume in the next step (3d >
standard) I cannot use the three step registration in FLIRT (low res > high
res > standard). Instead I do it stepwise, first T1 > 3D (no bet) and then
3D (skull stripped) > to standard. Then I apply the first .mat file to
transform my epi volume to 3d and then the second to standard. Now, to run
featregapply, I would need the transformation matrix
"example_func2standard". I have all the necessary information to transform
my epi data to standard, but in two .mat files. Can the
example_func2standard.mat -file be restored from the two matrices?
I guess one solution would be to transform all the cope and varcope images
to standard with the two matrices and then use cope images as input in the
higher-level analysis?
Thanks,
