call for help. 😅

I’m trying to use pet-must-segmenter, when I click perform segmentation, I got errors like below

Traceback (most recent call last):

ITK ERROR: GDCMImageIO(00000285738E9DB0): Cannot read requested file

how does this happen? I even cannot find the path and file “D:\D\P\S-0-build\ITK\Modules\IO\GDCM\src\itkGDCMImageIO.cxx”

I have tried to reinstall the software and modules, replace computers, it will be ok on my mate’s computer.

thank you for your help.

I used the sample data downloaded from github, after trying for one week, finally, I found the sample date does not work on my computer 💀. I try some other data, the module works well and I do not want to tangle with the sample data any more.
