RE: crash during PCA training

Hugues Fontenelle — Fri, 07 Feb 2014 10:43:33 GMT

I decided to build Slicer4 and the MABMIS extension. VS2010-SP1, 32-bits debug on Win7.

[b]I am using the provided demo data, and the extension crashes.[/b]

I am debugging to see exactly where the extension crashes.

In the trainging phase, things go fine until the "3. Build statistical deformation model...", in particular
the MABMISSimulateData::DoPCATraining
when it does[code]dfoperator->UpResampleDeformationField(intermediateSubDeformationFieldFileName,
intermediateDeformationFieldFileName, sampleRate);[/code]
FILE: itkMABMISDeformationFieldFilter.hxx
METHOD: UpResampleDeformationField()
LINE: # 452[code]ReadDeformationField(deformationFieldFileName, originImage);[/code]IS CALLED WITH PARAM
"temp_PCATraining8467\inter_deform_sub_000000.nii.gz"
and returns a null pointer in originImage, with leads the following
LINE #456[code]DeformationFieldType::SizeType im_size = originImage->GetLargestPossibleRegion().GetSize();[/code]to crash!

(My built version crashes at the same point than the one downloaded through the extension manager)

What am I doing wrong?
Thank you!

Looking forward :-)
I already posted a question in another thread.

crash during PCA training

Hello

It looks very promising.

I have the nightly Slicer4.3.1-2014-01-27 r22855 (64 bits) installed on my Windows 7 64-bits machine.

Slicer crashes when doing the training of the input data examples provided.
The testing part work fine (obviously only for the examples, since I did not manage to make any other atlases).

There is no particular error message; help me, how I can better describe the problem?

By the way, for the "Parameters for Atlas Training", "Training results", I provided a blank xml file which I created myself. Is that the way to go?
Thanks

Hugues
