Images with displacement greater than MAXPCT of a voxel will be omitted from further analysis (default MAXPCT = 50% for images, 30% if censoring volumes(flag 32)). If FLAG 0400 set, displacement minimum is default (50% img/30% vol) but that threshold is increased if necessary such that no more than MAXPCT of all images are censored. |
