Operating system:Ubuntu  
Slicer version:4.8.

Please can you help me in the multi CPU configurations to use with 3D Slicer. Is there any script that we can use?  
Thanks in advance

Can you give a bit more detailed description of what you would like to achieve?

Thanks for your fast reply. I would like to run UKF tractography for several subjects, using  
a computer cluster. Therefore I would like to know which are the needed configurations for the setup.

Hi @ssousa,

Here are few more questions that will help answer:

Are you able to install Slicer on the different node of the cluster ?

If not, is there docker installed on each node ?

Is there a shared filesystem or do you have to transfer the data to each compute node ?

Last, what do you use to orchestrate the job on your cluster ?

WE MAY USE A SHARED FILESYSTEM

USING A R or MATLAB SCRIPT on LINUX?
