Hi Sean,
Welcome to the MRSHub. I recommend the thread on building LCModel to get started on getting it to work on a local Windows machine.
Keep in mind though that LCModel only does one part of an entire MRS analysis workflow for you, the fitting. Data pre-processing and pulling in tissue segmentation information is not covered by it. Depending on what kind of analysis you need to do, you will need to either build an external pipeline around LCModel (which can be super tedious), or start with one of the open-source packages that live in the “Software & Code” collection of the MRSHub.
I’d highly recommend consulting with the experts here in the forum rather than setting out to do all this by yourself, especially given your relatively low experience with MRS.
Cheers,
Georg
