I have recently downloaded ITK-Snap and I am having issues loading an image. I get an error saying “vector too long” when trying to load a DICOM file from a MRI scan. I have no issue opening this same image in other software. Any help will be appreciated.

Can you share an example of a DICOM that produces that error (removing any PII, of course)?

Hi Dave, I have attached the DICOM image.

I looked at the image and didn’t see anything unusual about it. I was able to load it into SimpleITK and ITK-Snap without any issue.

Perhaps ask the developers of ITK-Snap? They have a mailing list here: [https://groups.google.com/g/itksnap-users](https://groups.google.com/g/itksnap-users)
