I would like to create an average subject from a very large population. I am going to compute it on a computer with a lot of threads and I would like to know if it is possible to parallelize the make_average_subject function to try to shorten the computation time. I have tried to add the -openmp flag but I get the error that the flag is unrecognized.

How can I solve this?

Thank you in advance.

Best regards,

Marina
