version 2.20 - Thu Jan 17 10:54:00 CEST 2017
Important warnings:
- Following a modification of orientation in the recording and reading of ROIs stored in Nifti in LIFEX 2.20, all ROI files recorded using a previous version should be flipped in the left-right direction and in the anterior-posterior direction after being read
