[Camino-users] datasynth ERROR with bvector scheme

[stefania oliviero]

Hi all users
I also have a problem with datasynth.
I'm using this command to generate a substrate.

datasynth -walkers ${WALKERS} -tmax ${TIMESTEPS} -geometry inflammation -numcylinders ${NUMCYL} -p 0.02 -initial uniform -seed ${INT_rnd} -voxels 1 -increments 1 -separateruns -latticesize ${LATSIZE} -schemefile ${SCHEMEFILE} -gamma ${GAMA} ${GAMB} -diffusivity ${DIFF} -substrateinfo -drawcrosssection ${FNAMEINFO}.gray > ${OUTPUTDIR}/${FNAME} 2> ${FNAMEINFO}.txt 

When I use a scheme file with a stejskaltanner format It works.
If I try to use a scheme file with a bvector format It doesn't work and the follow error appears:

Exception in thread "main" java.lang.ClassCastException: imaging.B_VectorScheme cannot be cast to imaging.SimulableScheme
    at tools.CL_Initializer.initDataSynthesizerFromSimulation(CL_Initializer.java:2031)
    at tools.CL_Initializer.initDataSynthesizer(CL_Initializer.java:2121)

    at apps.EntryPoint.getExecutable(EntryPoint.java:222)
    at apps.EntryPoint.main(EntryPoint.java:282)

The scheme file in bvector format is that downloaded from the tutorial DTI 4Ddwi_bvector.scheme:
#B-vector scheme. Contains gradient directions and b-values
#g_x	g_y	g_z	b

 What is the problem? Where am I doing wrong?
Thanks for interest.
