Hi,
I would like to report back regarding the recent unusual susceptibility distortion correction issue, with expanding brain to non-brain voxels.
I tried masking the magnitude images but there was no improvement in the results.
Based on the recommendation by @Marcel_Zwiers, here. I masked the phasediff image. I didn’t use the BIDScoin pipeline. I basically multiplied the phase-diff image with a masked-eroded magnitude image which I am also sharing with you. And the results look much better. I have used fMRIPrep version: 23.1.3.
Best,
Sevil.
