Hi all,<br><br> When I ran DeformableRegistration8 in ITK v4, I got output message like this:<div>...</div><div><div>27 -1.29292 0.000100976</div><div>27 -1.29292 9.59703e-005</div><div>28 -1.2929 9.59703e-005</div>

Probe Tag Starts Stops Memory (kB)</div><div> Registration 1 1 419332</div><div><div><br></div><div>The application stops and throws an error "<b>LBFGSBOptimizer: Failure</b>". In the source code of DeformableRegistration8, I set the parameters of optimizer such as "convergence factor" as this:</div>
<div><div><font color="#000099"> optimizer->SetCostFunctionConvergenceFactor( 1.e7 );</font></div><div><font color="#000099"> optimizer->SetProjectedGradientTolerance( 1e-6 );</font></div><div><font color="#000099"> optimizer->SetMaximumNumberOfIterations( 200 );</font></div>
<div><font color="#000099"> optimizer->SetMaximumNumberOfEvaluations( 200 );</font></div><div><font color="#000099"> optimizer->SetMaximumNumberOfCorrections( 5 );</font></div></div><div><br></div><div>Except the code above, I didn't change any code else. I have no idea what happened. Any suggestion would be appreciated.</div>
