Hi Jinny,
The sub-brick problem may have bitten you, but it's hard to
tell because there are some things that need fixing in your
commands.
In the 3dmerge command, you use -402 for vmul. But with a
negative value, that is translated into a number of voxels,
not vmul.
Since the output shows your voxels to be 2x2x2, that -402
should read -51 (ceiling of 402/8).
You also give a -1tindex option in exactly one of the
commands, but you specify a dataset, not an index. Since
your "index" is a string: "anova+tlrc[13]", that is probably
read as 0 by the program (which is the default, anyway).

Try the commands like this:
3dmerge -prefix XXX -1tindex 1 -1thresh 5.01 -1clust 2 -51 anova+tlrc"[12,13]"
3dclust -1tindex 1 -1thresh 5.01 2 402 anova+tlrc"[12,13]"
