Hi, Georg
Yes, my basis sets are generated by FID-A simulations. I tried the fit_makeBasis function and the io_writelcmBASIS function. It’s convenient.
Here are a few notes about creating MEGA-PRESS basis sets, just for reference.
1.As the last step of FID-A simulation, save both outON and outOFF in one .mat file for each metabolite.
2.Check the Matlab paths. Remove FID-A folders. （Functions such as 'op_gaussianPeak' share the same name in FID-A and Osprey, but have different content. ）
3.When using the 'io_writelcmBASIS' function to create ‘diff’ and ‘off’ basis sets, one may make the following modification:
In the line RF=shift_centerFreq(basisSet,i), change it to RF=shift_centerFreq(basisSet,i,subSpec). For the parameter subSpec, input 1 for ‘off’ or 3 for ‘diff’.
