Program hangs indefinitely after importing NIFTI file with 'Import medical images'

[juusokorhonen]

System: Ubuntu LTS 16.04
InVesalius 3.1.1

Steps to reproduce:

• Open InVesalius
• Select 'Import medical images...' from left-side panel
• Select a folder with .nii file that was used in NexStim navigation ssytem
  --> Error message appears: "There are no DICOM files in the selected folder."
  --> InVesalius hangs with window "Loading DICOM files"

This message cannot be dismissed, although pressing Cancel seems to refresh the sceen. Pressing 'X' on top left of window disables the Cancel button. Attempting to close InVesalius by right clicking the task bar icon and selecting 'Close' displays a confirmation dialog, but nothing happens after that. Attempting to kill the program with '$ kill ' gets rid of the process when viewed with '$ ps', but does nothing to the program window.

The only way to close the window is to use 'ps' to find the line 'python app.py' and kill that.

Dear @juusokorhonen ,
Thanks for the bug report. But for nifti import, you should use "Import other files..." menu (image below). Let me know if the crashs persists.

[juusokorhonen]

You are right in that the NIfTI import through the menu works. It is not an issue with the NIfTI import.

The issue here, is that trying to open a folder without DICOM files results in a unresponsive program that has to be forcefully quit through command line (in linux).

Furthermore, the tooltip message for the Import medical images suggests that you can open also NIfTI files. See attached screenshot.

Looks like is something related to linux. In windows it is working properly. @tfmoraes could you help with this issue?

@juusokorhonen thanks for the report. In the last commit I updated the tooltip to say it only opens dicom files. About InVesalius being unresponsive I think the folder you selected has a lot of files and/or a very deep hierarchy of subfolders. We use GDCM lib to check every file in the folder you selected and in the subfolder for DICOM files, it may take a lot of time.

[juusokorhonen]

Thanks for the suggestion. In this case, however, there is only the one nifti file in the folder and no subfolders. If you are interested, I could try to extract more information about the situation. Would there be something specific to check?

[tfmoraes]

@juusokorhonen you are running InVesalius from the source code, Ubuntu package, AppImage or Flatpak? What version? Could you share this file?

[juusokorhonen]

I am using the version from the InVesalius download page, GNU/Linux Ubuntu 16.04 64 bits, InVesalius-3.1.1-Ubuntu-16.04-amd64.tar.gz.

$ dpkg -l |grep ^i |grep invesalius

I tried running from the command line with invesalius3 -d, and I get some warnings during the startup, but nothing while the DICOM modal is running.

I tested this a bit further.

• The hanging/crash does not occur, if the folder is empty.
• The hanging/crash does not occur, if I browse to one folder higher in the hierarchy
• The hanging/crash does not occur, if there are other files (other that .nii) in the folder
• The handing/crash occurs, when I am in the highest folder in the hierarchy with only a single .nii file

If I create an empty file in the same folder, the hanging/crash goes away.

@juusokorhonen , please, could you try with version 3.1.999992? You could try the flatpak version https://flathub.org/apps/details/br.gov.cti.invesalius

[juusokorhonen]

It took me some time to install flatpak, but here are the results.

$ flatpak list
Description                                              Application                    Version   Branch Arch   Origin  Installation
InVesalius - 3D medical imaging reconstruction software  br.gov.cti.invesalius          3.1.99992 stable x86_64 flathub system

I can confirm that this version has the issue fixed.

However, I had to give extra permissions to invesalius by running from command line:
$ flatpak --filesystem=host run br.gov.cti.invesalius

This is because my data resides outside my home directory.

[tfmoraes]

Ok. Thanks for testing. I'll close this issue and I'll take a look at this issue with flatpak. Thanks!
