SimVascular Crashes during ML segmenting

[Srihari Menon]

Hello,
I'm trying to segment using the multi-vessel path approach. Every time I press the 'Segment using Machine Learning' button, SV starts processing, then gives out an error and crashes. Attached is a snapshot of the terminal shortly before crashing. The last error displayed is "error SVWrapper not loaded" and "Error setting image, sv_wrapper returned null".

Any ideas on what may be wrong?

Hi Srihari,

Thanks for letting us know about this. Could you let me know the following information:

* What kind of image data are you using?
* What file format is the image?
* How are you loading in the image?

Then could you also let me know

* What operating system are using?
* What version of SimVascular are you using, is it the latest one?

Best,

Gabriel

Hey Gabriel,

1. I'm studying MRI scans (not sure if thats what you're exactly asking)
2 and 3. I import them initially as .dcm files, but save them in SV collectively as one .vti file. Then once i fire up the SVproj file I think the .vti files are loaded (but i don't actually know where SV is loading the image files from subsequent to the initial import).

I'm operating SimVascular Version 2019.07.10 on windows 10.

Hi,

Please upgrade to the latest Windows release (August 9) as there is a fixed issue related to ML.
