[VoxBo] new vbxts tool just in time for weekend fun

[Daniel Y Kimberg]

Hi all.  I've just put a test version of a new VoxBo utility up on the
ftp site.  The tool is vbxts (extract time series), and it lets you
extract one or more time series worth of data from either a GLM or a
set of tes files.  It provides options for filtering, converting to a
power spectrum, detrending, mean scaling, averaging, and choosing
either a single voxel or a mask.  More options are coming.  It puts
the output in a ref file (currently named automatically and not that
cleverly).  You can have multiple masks and multiple averages to have
it do a lot of work at once.

The program is pretty rough, but works well for me so far.  I'm
putting it out there in its current form because I think it might be
helpful to anyone who won't get too upset at some rough edges (e.g.,
it crashes if you give it a mask with no voxels, and writes its output
silently), and also I'd like some feedback.  I know it's missing many
useful features, but it's already reasonably useful, and there's been
some demand in the past for a tool like this.  If you do use it,
please drop me a line to let me know how it worked for you.

It's installed at the CfN, if you're elsewhere you can find it at:

ftp://voxbo.org/pub/voxbo/alacarte/linux/vbxts

This build is for "modern" linux systems -- I'm partway through
rebuilding our "legacy" build box, and we'll soon have versions for
OSX and Cygwin as well.  If you're desperate to get this on another
platform, let me know and I'll build it for you.

Note that this is a completely new tool, not derived from an earlier
hack of the same name, which had limited distribution and limited
functionality (yet did have a few features as yet missing from the new
version).
