Hi!

I was following the video tutorial 02 Testing OD3D and am facing a weird issue when I select the Utilities → Run Test. I receive the following message on the Python console:

Could you help me with what could be causing this?

Is the Elastix extension installed? There is an error about not finding the directory:

```auto

Hi,

I checked and it is installed. The name of the module tho that appears to me is SlicerElastix.

It is not finding the registration presets. That looks like an issue with Elastix to me. Perhaps try running the Elastix by itself to register a dataset and see if it is correctly installed?

Hi,

I tried running Elastix by itself and it shows me this message on the python console:

[Python] Cannot load preset. Loading failed with error: [Errno 2] No such file or directory: ‘/home/administrator/Software/Slicer-5.6.2-linux-amd64/slicer.org/Extensions-32448/SlicerElastix/lib/Slicer-5.6/qt-scripted-modules/Resources/RegistrationParameters/par0013Powell\_NGC\_singleImage.txt’

I am confused because the file exists and it’s present in that directory.

At least you know the issue with Elastix. I am not familiar with unfortunately.  
So in the shell window if you do

`ls -l /home/administrator/Software/Slicer-5.6.2-linux-amd64/slicer.org/Extensions-32448/SlicerElastix/lib/Slicer-5.6/qt-scripted-modules/Resources/RegistrationParameters/par0013Powell_NGC_singleImage.txt`

you see a file?

Yes I see. I even went to the directory itself and opened it.

administrator@Pacheca-IBEB:~$ ls -l /home/administrator/Software/Slicer-5.6.2-linux-amd64/slicer.org/Extensions-32448/SlicerElastix/lib/Slicer-5.6/qt-scripted-modules/Resources/RegistrationParameters/Par0013Powell\_NGC\_singleImage.txt

I think I see what is wrong. My file is called Par0013Powell\_NGC\_singleImage.txt while the one 3d Slicer is trying to find is par0013Powell\_NGC\_singleImage.txt. it’s all because of the letter P.  
I just changed to a small letter p the name of the file and I don’t get the error for Elastix.

Dear @imbeatriz ,

For version 5.8.0, its more better for OpenDose3D. Perhaps you try it. Especially in OAR segmentation, very nice.
