Hi,
I’ve also been looking for a basis set for this sequence last year and spent a few months trying to find one - but unfortunately without success. After that, I shifted my focus to other projects for a while, but I’m now continuing with this one and have started teaching myself how to simulate a basis set for our specific scanner setup (we had to adapt the excitation pulse duration).
This was the thread I posted back then: 3T Siemens CMRR sLaser & Mega sLaser (for GABA) Basis Sets - #7 by Thomas
I used the sequence description from @wclarke to simulate the basis set with FSL-MRS and created the JSON files – which seems to have worked. However, I’m now running into the issue that I’d like to use Osprey and don’t know how to convert the FSL-MRS JSON metabolite files into a format that Osprey can read. I’ve tried a few approaches, but haven’t been successful so far. Any guidance on how to convert these for use in Osprey would be greatly appreciated.
I’ve also been thinking about simulating the basis set with FID-A, but I’m not sure how to use the sequence description/pulse info from @wclarke to do that. Any tutorials, examples, or suggestions would be super helpful.
Thanks a lot for the great resources and support you provide!
