Border lines in some images #14

Hi Korbinian! I have had a QSMxT user approach me with an issue with the generated SWI from CLEAR-SWI - there are border lines visible on the output that, to my understanding, do not appear in the input images.

Could this be related to the sensitivity correction step? Do you know if there are setting that should be changed for this particular dataset? Thanks so much!

Hi Ashley! This looks weird, I haven't seen it before. The homogeneity correction is designed for brain images, but it should always produce a smooth bias field and not be this wrong. So it's a bug, I want to fix it ;) Can you send this dataset?

If you want, you can try to deactivate the sensitivity correction with the keyword argument: mag_sens=[1]

Thanks for the suggestion! I'll see if I can get the input data to test that option and to send through.
