I have run FSL on a PC using the Linux compliation, and on a SGi with the
IRIX version. I received slightly different results: the images looked
very similar, but the max Z values were 5.940 vs. 5.943 and the number
voxels for the contrast was 2026 vs. 2038 (the 5.943 and 2038 were from the
linux version). Any explanation? So I worry about it? Our local computer
guru guessed that it might be that the PC is using greater than the IEEE
standard precision, where the SGI uses the standard.
