Hi Resonint Team, I’ve been getting into making some pulse sequences recently. One thing I thought would be helpful is to make a helper library of gradient shapes (attached) - ramp, trapezoid, triangle, sinusoid.

Hey there, How is the RF amplitude defined within the jupyter notebooks? It appears to be in arbitrary units, for example, in the RARE sequence’s 180° block pulse, the amplitude is set to “1”, which I back-calculated to… --- ## [Maximum RF amplitude](https://resonint.discourse.group/t/maximum-rf-amplitude/65)
