Jian:
The user must specify 1 and only 1 sub-brick with each -dset command.
That is, if an input dataset contains more than 1 sub-brick, a sub-brick
selector must be used. This is the case for the FIM+ output, which contains
4 sub-bricks. The sub-brick is specified by enclosing the index number in
square brackets; e.g., 'fred+orig[3]' indicates sub-brick #3.
1st NOTE: The sub-bricks are numbered beginning with 0.
2nd NOTE: The square brackets must be enclosed within quotes.
For example, if you want to select the first sub-brick as the input for
each of your datasets, you could use:
-dset 1 1 'mc_601KM_mech_LL@1+tlrc[0]' \
-dset 1 1 'mc720TW_mech_LL@1+tlrc[0]' \
-dset 1 1 'mc825AC_mech_LL@1+tlrc[0]' \
-dset 2 1 'mc_601KM_mech_LH@1+tlrc[0]' \
-dset 2 1 'mc720TW_mech_LH@1+tlrc[0]' \
-dset 2 1 'mc825AC_mech_LH@1+tlrc[0]' \
-dset 1 2 'mc_601KM_mech_RL@1+tlrc[0]' \
-dset 1 2 'mc720TW_mech_RL@1+tlrc[0]' \
-dset 1 2 'mc825AC_mech_RL@1+tlrc[0]' \
-dset 2 2 'mc_601KM_mech_RH@1+tlrc[0]' \
-dset 2 2 'mc720TW_mech_RH@1+tlrc[0]' \
-dset 2 2 'mc825AC_mech_RH@1+tlrc[0]' \
etc.
One additional comment: The output bucket dataset will contain a number of
sub-bricks (20). Since these are tlrc sub-bricks, this will consume quite
a lot of memory. My concern is that your computer may have difficulty in
assembling all of these sub-bricks into the one bucket dataset. If this is
the case, you may have to write the output as separate 2 sub-brick datasets
(by eliminating the -bucket command). Alternatively, you could reduce the
amount of output that you request. There is some redundancy in the output
that you have requested (since there are only 2 levels for factors A and B).
