Hi, all.
I want to use Matrix for constructing structural connectomes of stroke patients.
Please let me know what specs I need for the PC for MRtrix. For example, graphics, RAM, CPU, etc.
Please give me any advice about setting up.
Thank you so much.

There’s a few threads on the issue on the forum, the general recommendations haven’t changed on all that much. The main thing I’d watch out for is to ensure you have a decent NVIDIA GPU on board, since that means you can use the CUDA version of `eddy`, which will massively accelerate `dwifslpreproc`. Otherwise, take a look at these posts:

> Yes, with the possible exception of tcksift if running with more than ~10 million streamlines – it’s quite memory-intensive… The other memory-hungry application is fixelcfestats (the statistics for fixel-based analysis), which can require 64-128GB… I’d say try it without, and upgrade if you need to. However, if you know you intend to use tcksift / tcksift2 (which I’d recommend), I’d install the extra RAM now. Yes, within the same limitations as above, and depending on your input data. For …

> Hi @jramend, Myself and @jdtournier are both Arch Linux users nerd, and I’d hazard a guess that any other Linux machines used by developers are probably Ubuntu. Personally I’m using xfce as my WM, kernel 4.4.48-1-lts on a single GTS 250 (LTS kernel required to keep the older 340.xx video drivers working). Are you attempting to use bumblebee or similar to deal with the multiple GPUs? I believe @Dave has some experience with that. It might be worth copy&pasting your configure script log (mak…
