1.5.9 (February 14, 2020) Bug-fix release in the 1.5.x series. This release fixes a bug for some phase maps generated by Philips. A full fix with better handling of all phase maps will be available in an upcoming minor release (20.0 or 20.1), but this should permit users who are processing with 1.5.x to resolve this issue in a way that does not affect phase maps unaffected by the bug. * FIX: Center phase maps around central mode, avoiding FoV-related outliers (poldracklab/sdcflows#89)
