Hello everyone,

I want to install Simvascular on my computer but I have a problem. When I try to install Simvascular, it seems working, but after the installation process, when I launch the software by double-clicking the icon, nothing is happening. I am using ubuntu 19.04

Thank you in advance for your help.

Hi Guillaume,

Open a terminal and run /usr/local/sv/simvascular/2019-03-17/simvascular, this will display the cause of the failure. Post that here please.

The Ubuntu installer was built for Ubuntu 16 and 18. I am guessing that SimVascular is not able to find the correct version of libssl.so for Ubuntu 19.

Cheers,
Dave

Thank you Dave for your answer,

I have change my ubuntu version, I have now ubuntun 18.04, and SimVascular is working well.
I only have one problem : every time I want to change the Lofting Parameters, in the SV 2D Segmentation menu, in single path-path, it shut down SimVascular. I do not know if this bug has already been reported.

Thank you again,

Guillaume

Hi Guillaume,

Glad you are up and running!

I have not heard of a SV crash when changing Lofting Parameters. Which parameters are you changing? Attach an image of your segmentations, it might be that the segmentations are intersecting and SV is crashing when trying to create the loft geometry. Also open a terminal and run /usr/local/sv/simvascular/2019-03-17/simvascular, this might display the cause of the failure.

Cheers,

Hi Dave,

Sorry I have been so slow to answer, I think the problem just occur when you click on the Lofting parameters button in the SV 2D Segmentation without any segmentation contour selected. But it is working if I select a segmentation contour in the first place.

Thanks again,

Guillaume

Hi Guillaume,

Now I understand the problem! When you start SV there is an SV 2D Segmentation tool panel displayed that is not associated with any contour group. When you click on the Lofting Parameters button SV crashes.

I've created a GitHub Issue for this (https://github.com/SimVascular/SimVascular/issues/521).

Thank you Dave,

I am sorry to bother you again but I have a new problem : I cannot open DICOM images with Simvascular on my ubuntu 18.04 with Open File, and as the MITK DICOM Browser do not exist on the ubuntu version I can't use it. I have tried on Windows because the MITK DICOM Browser exist in it but after loading all of the images I can't open the file I have created and an error message pops up. I have tried to upload my Dicom images withe the MTK DICOM Browser and every time this message pops up, even if I try to reboot Simvascular Attached are some screen shots.

Thank you in advance,

Guillaume

Hi Guillaume,

Where you able to create a project and read in the image files (right click on Images->Add/Replace Images)?

Is your data CT or MRI?

Cheers,
Dave

Hi Dave,

I can't read the images with right click on Images->Add/Replace Images after creating a SV project on ubuntu 18.04.
My DATA is a MRI.

Thank you in advance,

Guillaume

Hi Guillaume,

It's not clear what's going on here. We have just recently found some problems with the MITK DICOM reader for CT data but I have not seen any problems with MR. Your data is detected as MR but then a reader can't be found for it so I'm thinking that there is a formatting issue with your data that MITK is not handling correctly.

If you can put your image data someplace I can download it (just a few slices would be fine) I will have a look. You could also convert the DICOM data to VTI using vmtk.

Cheers,
Dave
