Hello I am attempting to run a 4-way ANOVA repeated measures ( type 2 ) and i keep getting this same error:

"Subscripted assignment dimension mismatch"

The command lines are below.
Total slices along Z axis: 151 - You can estimate the total runtime
by multiplying the runtime for each slice from down below.

Running analysis on slice:
#1... ??? Subscripted assignment dimension mismatch.

Error in ==> /usr/MRITools/matlab/afni_matlab/matlab/GroupAna.m
On line 1672 ==> [err, X(:, :, i), Info, ErrMessage] = BrikLoad(file(i).nm, Opt);

Your help would greatly be appreciated. If you need additional details please let me know.

Its a pretty lengthy list of commands due to the number of factors and levels. I'll post the the beginning lines below:

Groups analysis for volume or surface data (0 - volume; 1 - surface)? 0

How many factors? 4

Availabe design types:

Type 1: Factorial (crossed) design AXBXCXD - all 4 factors are fixed.

Type 2: Factorial (crossed) design AXBXCXD - only factor D is random. If D is subject it is also
called 3-way design with all 3 factors A, B, and C varying within subject.
Type 3: Mixed design BXCXD(A)- only the nested (4th) factor D (usually subject) is random.
Also called 3-way design with factors B and C varying within subject and factor A between subjects.
Type 4: Mixed design BXCXD(A)- D is nested within A, but only the 3rd factor (usually subject)
is random.
Type 5: Mixed design CXD(AXB) - only the nested (4th) factor D (usually subject) is random,
but factor D is nested within both factors A and B. If D is subject it is also called 3-way
design with factor C varying within-subject and factors A and B between-subjects.
