We’re having some disk and network problems, so no SVN access for now. Apologies for any inconvenience. 

Annotated output for double2txt etc

It can be hard to read the standard output from double2txt and related programs, so you may now add line or voxel numbers.

Updated pig tutorial

I fixed the scheme file and updated some of the commands to use newer programs. A bit less typing required to do things now than when this tutorial was first written.

New tutorial

Danny has put up a new tutorial on tractography with q-ball / PAS MRI data.

The visualizations shown in the tutorial are done with Geomview (OOGL format), but the tracts could also be displayed in VTK via the vtkstreamlines command.

scheme2fsl now converts any scheme format

scheme2fsl previously only converted version 0 scheme files - in r846 it will now work with any Camino scheme format and produces the FSL bval / bvec files.
