Hi James,
It's not possible (currently?) to get snapshots with Freeview or the
tktools without invoking X. I can post a link for the modified script
which uses Freeview instead of the tktools. It's much slower though and
until the movie frame capture is a commandline option, using the tktools
is probably best.
Just stumbled upon xvfb which might do the trick.

Dear Louis,
Thank you for your comprehensive response, the QA tools are certainly valuable
tools. I'm very curious on how I
could go about getting Freeview snapshots without invoking X. I was wondering
whether you are happy to share
your "alternative version which gets snaps with freeview"? Or perhaps more
generally, how a programmer should
approach this problem of not invoking X when getting the snapshot?
Thanks
James

Hi James,
Freeview has a "Write Movie Frames" option which will grab multiple
screenshots throughout a
volume. I recently requested a commandline option for this. I've run into the
"no X11 on cluster"
limitation as well, and I don't have a work-around at this point.
The snapshot-to-html script is roughly implemented in the set of QATools
scripts using tkmedit. I
have an alternate version which gets snaps with freeview, but it runs
faster with tkmedit at this
point.

Dear all,
I'm looking for a way to automate surface on volume
visualization, to check
if the surface reconstruction have been successful on a very
large number
of
subjects. Normally, I would use freeview with -f and -v flags
to check and
see if it is necessary to edit controls points, etc.
As an example, one option to automate this process is to use
freeview
snapshot option and write a script that runs on several
hundred subjects
and
then show all the resulting images in html format. Running
freeview with
snapshot option works really good, however, since every
freeview run needs
X11 there is an overhead here, especially when I'm running on
a remote
cluster with no X11, which makes running X11 almost
impossible.
I'm wondering whether any one has a better idea for this?
Thanks
James
