Howdy,

I'm having trouble with the new -gltsym option. The following:

-gltsym 'SYM: +pa.obs[[0..10]] -fa.obs[[0..10]]' -glt_label 1 pa-fa.obs \

yields this error:

"** ERROR: sub-brick index 10 is out of range 0..9"

and the following matrix:

"GLT matrix from 'SYM: +pa.imit[[0..10]] +fa.imit[[0..10]] -tha.imit[[0..10]] -ta.imit[[0..10]]':
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 0 0 0 0 0 0 0 0"

I had expected the matrix to have 11 rows (for a maxlag of 11) and a 1 and -1 in each row based on the example given @ [afni.nimh.nih.gov].

I noticed that, for example:

-gltsym 'SYM: +pa.obs[[0]] -fa.obs[[0]] \ +pa.obs[[1]] -fa.obs[[1]]' -glt_label 1 pa-fa.obs \

would actually make the hoped for matrix if we actually wrote the whole thing out but this would be a lot of work.... Did we not use the right format at first?

Thanks mucho,
Jeremy
