if you have multiple cores you can use -openmp <N> which gives a pretty good speed increase up to about N=4 or 5

Thank You. It's working now. But I can see the execution time is really slow. Is it possible to make it faster using CUDA or any other way?

If you are using RedHat/CentOS linux,

$ sudo yum install tcsh

Fedora linux

$ sudo dnf install tcsh

Ubuntu/debian linux,

$ sudo apt-get install tcsh

I would also probably install csh the same way as well.

Hi  freesurfer,  I am following the installation test as suggested (

https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall and am currently stuck at example 2. When I ran recon-all, I got the output:

"bash: /home/sghos003/freesurfer/bin/recon-all: /bin/tcsh: bad interpreter:

No such file or directory"

Any suggestions? Thank you.
