Dear FSL experts,
I run POSSUM simulation in High performance computer center (hpcc). When I view the final result (image_abs.nil.gz) in fslview, the image is not a whole brain but 12 slim slices. I guess that it may be caused by parallel computation, since I get a whole brain image when using one CPU. I did the simulation by using parallel computing (12 CPUs). I do not know how to integrate them and make it look like a whole brain. Does anyone know how to solve this problem?
Another question is when I view the final result (image_abs.nil.gz) in fslview by using movie mode, it always flashes at volume 0, no matter how many volumes it has. Is it a common phenomenon?
I listed my parameters as below for reference. Thank you very much in advance.
