Dear Doug,
the subject with leak of white surface outside brain (my first post with
screenshots) is subject 1. Slice number (coronal) around 100.
The subject in second post (with text below) is subject 2, slice number
(coronal) also 100.
I have processed the subjects with v 6.0 (in fact dev version from feb 2017,
but this is irrelevant) with -cubic -no-mprage. It looks much like v5.3, i.e.
the wm.mgz and surfaces are much better, but v5.3 looks still better, at least
for subject 1.
I have uploaded them as file v6.0_cubic_no_mprage.tar.gz to your ftp site.
The optical difference in norm.mgz/brain.mgz between v5.3 and v6.0 with -cubic
is very minor, but still there is some other thing which renders wm.mgz worse
than with v5.3 for subject 1.
The -cubic has profound effect, the images seem much smooth with lose of
contrast without using -cubic.
Regards,
Antonin
And what slice number?
