RE: batch & multiple between conditions contrasts
Alfonso,

Thanks for your suggestions.

If I'm running an entire batch procedure in one script, (setup, preprocess, analysis, results), would I have to designate the BATCH file in 3 parts as below?

I ran everything as such:

BATCH.Setup= 
.
.
BATCH.Preprocess
.
.
.

But then I created the 3 part setup for the Results

BATCH(1).Results...
.
.
.
BATCH(2).Results...
.
.
.
BATCH(3).Results.

I ran the batch procedure and it successfully excuted my first contrast Cond_A vs Cond_B, but when it tried to execute the 2nd contrast, Cond_A vs Cond_C:

I received an error message stating:

Error using dir
Function is not defined for 'double' inputs.


I think the problem is the 2nd and 3rd elements of the BATCH structure array. It contains the Results field information for the remaining 2 elements, but no *.mat filename, Setup, Preprocss, or Analysis information in the respective fields. Should I just  include two additional lines in the batch script:

BATCH(2).Results.filename="name_of_conn_mat_file.mat";
BATCH(3).Results.filename="name_of_conn_mat_file.mat";

Would this solve the problem? Or do I need to include additional code?

Thanks again,

h.

Yes, you can enter an array of BATCH processes simply by having the variable 'BATCH' defined as a structure array. For example:

clear BATCH;
BATCH(1).Results.between_subjects.effect_names={'AllSubjects'};
BATCH(1).Results.between_subjects.contrast=[1];
BATCH(1).Results.between_conditions.effect_names={'Cond_A','Cond_B','Cond_C'};
BATCH(1).Results.between_conditions.contrast=[1 0 -1];
...
BATCH(2).Results.between_subjects.effect_names={'AllSubjects'};
BATCH(2).Results.between_subjects.contrast=[1];
BATCH(2).Results.between_conditions.effect_names={'Cond_A','Cond_B','Cond_C'};
BATCH(2).Results.between_conditions.contrast=[1 -1 0];

...
conn_batch(BATCH);

Hope this helps
Alfonso

Hello,

I have question regarding multiple between conditions contrasts using a batch script, is this possible?

We have 3 conditions, A, B, and C.

Here is an example setup:

BATCH.Results.between_subjects.effect_names={'AllSubjects'};
BATCH.Results.between_subjects.contrast=[1];
BATCH.Results.between_conditions.effect_names={'Cond_A','Cond_B','Cond_C'};

For the contrast, Cond_A > Cond_C, I choose the following:

BATCH.Results.between_conditions.contrast=[1,0,-1];

This is correct, no?

If so, is there a way to set up the BATCH.Results.between_conditions.contrast file where 3 contrasts are provided as input:

Cond_A vs Cond_C   [1 0 -1]
Cond_A vs Cond_B    [1 -1 0]
Cond_B vs Cond_C  [0 1 -1]

And the output folder contains 3 subfolders, one for subfolder for each contrast?

Essentially, can we setup the batch to run similar to SPM's contrast manager where you can enter several contrasts as opposed to just one described in the conn toolbox manual?

Thank you,


h.
