FSL-MRS Basis Conversion for SPANT

Analysis / Modeling Basis Sets
1

Hi, I would like to convert a basis generated with FSL-MRS (.JSON format) to a SPANT-compatible format, since I develop my MRS pipeline in R for statistical analysis.

Thanks in advance !

Hi Clement,

Happy to take a look. Could you send me what you have so far? I’m not familiar with the .JSON format for storing basis sets.

@wclarke is there a way to export basis sets as set of NIfTI MRS files? spant has two functions (read_basis_niidir and write_basis_niidir) for dealing with this storage method.

@martin Sorry there isn’t, given that the basis standard format never quite got there I didn;t get around to implementing it. The files are very simple, they are just a directory with a JSON for each metabolite storing the FID, there is a field for real and imaginary data, the dwell and the central frequency.

thanks @wclarke, I see examples at : William Clarke / WIN MRS Basis Sets · GitLab so shouldn’t take long to implement a reader…
