Hi,

I would like to ask about 3dLME GLT coding.
I just bring the 'example 3' from '3dLME' instruction on the web as following.

3dLME -prefix Example3 -jobs 24 \
-model "cond*group" \
-ranEff '~1' \
-SS_type 3 \
-num_glt 6 \
-gltLabel 1 'pos-neu' -gltCode 1 'cond : 1*pos -1*neu' \
-gltLabel 2 'neg' -gltCode 2 'cond : 1*neg ' \
-gltLabel 3 'pos+nue-neg' -gltCode 3 'cond : 1*pos +1*neu -1*neg' \
-gltLabel 4 'pat_pos-neu' -gltCode 4 'cond : 1*pos -1*neu group : 1*pat' \
-gltLabel 5 'pat_neg-neu' -gltCode 5 'cond : 1*neg -1*neu group : 1*pat' \
-gltLabel 6 'pat_pos-neg' -gltCode 6 'cond : 1*pos -1*neg group : 1*pat' \
-num_glf 1 \
-glfLabel 1 'pos-neu' -glfCode 1 'Group : 1*ctr & 1*pat cond : 1*pos -1*neu & 1*pos -1*neg' \
-dataTable \
Subj cond group InputFile \
s1 pos ctr s1+tlrc'[pos#0_Coef]' \
s1 neg ctr s1+tlrc'[neg#0_Coef]' \
s1 neu ctr s1+tlrc'[neu#0_Coef]' \
...
s21 pos pat s21+tlrc'[pos#0_Coef]' \
s21 neg pat s21+tlrc'[neg#0_Coef]' \
s21 neu pat s21+tlrc'[neu#0_Coef]' \

My question is if these following GLT coding would provide the identical t-test result.

1) -gltLabel 1 'pos-neu' -gltCode 1 'cond : 1*pos -1*neu' \

2) -gltLabel 7 'pos+nue-neg+neg' -gltCode 7 'cond : 1*pos +1*neu -1*neg -1*neu ' \


I assumed that in the second case condition 'neu' should be cancelled out.
I have tried this way with my data, but these two gave me the different result.
Could you let me know what happen in this coding?


Thanks

Jung
