Hi @HSun981! gradient_waveforms function is removed, which made calculate_kspace non-functional (should be removed as well). You can see the discussion here: #107 and #109.

It is replaced by calculate_kspacePP function, which should work as a drop-in replacement.

If you really want to use calculate_kspace or gradient_waveforms, you can add those functions separately to your project with slight modifications to the code shared in PR #109.

I am closing this issue as there is already an open issue related to this, but if you have more questions/comments, feel free to comment to the original issue.
