Hello,

I have noticed that the SlicerIGT tutorials have been updated recently (specifically Lesson U-01). In this tutorial, it states that one of the extensions to download is SlicerIGSIO. When searching in the extension manager I was unable to find this extension. I was wondering if we have to directly download it from github, or if there is another work around. Anyway I would like to thank you for taking the time to read this and I look forward to your response.

What version of Slicer are you using?

SlicerIGSIO appears to have built successfully on the latest nightly release (4.11), but not the stable (4.10.2).

Hello Kyle,

I am currently using the stable release (4.10.2) which would explain why it is not showing up. Thanks for the reply!

@Sam_Horvath Do you have an idea of why the stable version of SlicerIGSIO is failing?

The build seems to be running into issues while checking out one of the projects:

Yeah, I have been looking at it. This git-submodule issue seems to appear randomly on Windows and I haven’t found a consistent solution for it. I am going to try to force / hack around this on the stable build so we can get at least one working upload for IGSIO.

So, I have forced a build/package/upload for SlicerIGSIO on stable, vs the current SlicerIGSIO master. I will continue to look into the actual build issue, but it is not something I have had any luck in fixing in the past.
