Newer versions also have the ability to run some stages on multiple CPU cores (with the -openmp <cores> flag) which speeds certain stages (e.g. in autorecon2) up considerably. I'm also sure Bruce wouldn't turn down more resources to hire the programmers needed to make it faster either!

Peace,

Matt.

Hi Tanya we have always preferenced minimizing manual interactions over computer time. It takes so long because of its level of automation and its completeness. This is also why it is so widely used I assume - because it generates a comprehensive, accurate and automated morphometric assay of the human brain. Seems like waiting a few extra hours to get something complete, automated and accurate isn't a big deal.

Hi, I would like to ask that why does the Freesurfer takes so much time for processing particularly autorecon2 ?

Knowing that Freesurfer takes a lot of time for processing, why is it still used widely by researchers ? For segmentation followed by volume calculation , does one has to really wait for hours for the results?

Thank you
