I found the cause of the first issue.
There is a loop in the itkGibbsTrackingFilter.cpp file:
float alpha = log(m_EndTemperature/m_StartTemperature);
m_ParticleWeight = 0.01;
int ppv = 0;
// main loop
int neededParts = 3000;
while (ppv<neededParts)
{
if (ppv<1000)
m_ParticleWeight /= 2;
else
m_ParticleWeight = ppv*m_ParticleWeight/neededParts;
encomp->SetParameters(m_ParticleWeight,m_ParticleWidth,m_ConnectionPotential
*m_ParticleLength*m_ParticleLength,m_CurvatureThreshold,m_InexBalance,m_Part
iclePotential);
for( int step = 0; step < 10; step++ )
{
// update temperatur for simulated annealing process
float temperature = m_StartTemperature *
exp(alpha*(((1.0)*step)/((1.0)*10)));
sampler->SetTemperature(temperature);
for (unsigned long i=0; i<10000; i++)
sampler->MakeProposal();
}
ppv = particleGrid->m_NumParticles;
particleGrid->ResetGrid();
}
I found the ppv¹ was never bigger than 3000. The biggest number I have
about 2500. Because I used skull-stripped brain that caused the issue. No
problem if I used whole head instead.
The question is which one is better, whole head or brain-only DTI? If I use
the brain-only DTI, what suitable value is for neededParts?
Thanks,
Wayne
