Hello, All members in 3D-Slicer

Maybe… Have you ever used the Slicer-DeepSeg extension?

I’m reproducting extraction of brain tumor using Slicer-DeepSeg extension based on 3D-Slicer.

I’m running DeepSeg extension using MICCAI\_BraTS2020\_TrainingData in 3D-Slicer refering to Slicer-DeepSeg github.

I ran the Slicer-DeepSeg extension in 3D-Slicer as following.

1. Creation of Slicer-DeepSeg Extension/DeepSeg module  
1)I run ‘Extension Wizard’ module-\>2)Select ‘Select Extension’ button-\>3)Select ‘Slicer-DeepSeg’ folder-\> 4)Select whether ‘DeepSeg module’ loads or not

2. I downloaded dataset  
-MICCAI\_BraTS2020\_TrainingData

3. I run DeepSeg module using MICCAI\_BraTS2020\_TrainingData in 3D-Slicer  
(1) After pressing ‘Add Data’ button in ‘Welcome to Slicer’ module, I imported ‘BraTS20\_Training\_001’ folder in MICCAI\_BraTS2020\_TrainingData.  
(2) And then I selected ‘DeepSeg’ module in ‘modules finder’ option.  
(3) In Inputs item, I selected ‘BraTs20\_Training\_001\_flair\_1’ in ‘FLAIR Volume’ option.  
(4) In Outputs item, I selected one volume (MRI) dicom file in ‘Tumor Volume’  
(5) I set the different options in ‘Advanced Segmentation Parameters’ item as following.:

After completing setting using DeepSeg module in 3D-Slicer, I pressed ‘Apply’ button.

But It occurs the error that is “Failed to compute results: Incomplete or corrupted file detected. The sha256 file hash does not match the provided value of 941eb4b2c7da98310a95176e7adabe8f84d2e3df.  
Traceback (most recent call last):

raise ValueError(ValueError: Incomplete or corrupted file detected. The sha256 file hash does not match the provided value of 941eb4b2c7da98310a95176e7adabe8f84d2e3df.”.

I guess you refer to code from [this repository](https://github.com/razeineldin/DeepSeg). Best to file an issue there.
