Hello Everyone,
I'm facing this error right now..

Sorry if this error is a newbie mistake... :(

Changes that i make is on the data_root path and save_folder path as below...

data_root = /home/zaaba/anaconda3/brats17-master/Brats17TrainingData
save_folder = /home/zaaba/anaconda3/brats17-master/Brats17TrainingData/result17
data_names = config17/test_names_temp.txt

Hi zaabahmad,
Can you make sure the output dir exists? You need to create that dir manually as the code does not create it automatically.

[zaabahmad]

Hi taigw,
Thank you for responding. The output dir did exists as i have manually create it.
As below configuration.
data_root = /home/zaaba/anaconda3/brats17-master/Brats17TrainingData
save_folder = /home/zaaba/anaconda3/brats17-master/Brats17TrainingData/result17
data_names = config17/test_names_temp.txt

should i change it to this instead?

data_root = /home/zaaba/anaconda3/brats17-master/Brats17TrainingData
save_folder = /home/zaaba/anaconda3/brats17-master/Brats17TrainingData/result17
data_names = /home/zaaba/anaconda3/brats17-master/config17/test_names_temp.txt

I got the same error, if you have fixed it the bug, can you please tell me the way how to correct this error?

[taigw]

@zaabahmad In your first question, it seems that you were trying to save the data to ''/result17". I guess you intended to save it in "./result17".

[taigw]

@TigabuYaya Have you solved the problem?

I'm having this same problem when trying to write my output data:

** ERROR (nifti_image_write_hdr_img2): cannot open output file 'result18/HGG/Brats18_CBICA_ATX_1.nii.gz'

My test_all_class.txt file reference scheme is the same as your example in config17.

[Resolved]: You have to make the directory containing HGG/LGG results programmatically before writing to this directory in save_array_as_nifty_volume(..) in data_process.py

[jcai10]

For my case, there is no enough disk space.
