Image data error

[LynnHg]

Hello, @neheller ,
Thanks for organizing this great challenge!.

I have downloaded all the image data, like 'master_00000.nii.gz', 'master_00001.nii.gz'...'master_00299.nii.gz'.
But I find that all the data cannot be unzip, when I tried to unzip it, it said, "checksum error, this file is corrupted."
I've downloaded it again twice.
Would you mind tell me how to solve it?

To be honest I've never attempted to unzip this data explicitly, I always just let the relevant image viewers/readers do that. What's your goal with the data? If you'd like to read it into Python, the nibabel package should be able to do that without first uncompressing. You can find an example of this in starter_code/visualize.py. If you're just trying to view the images, ITKSnap should also be able to open the files without uncompressing first.

Thanks foy your suggestions.
In fact, I have tried to use ITKSnap to view the images, and the image files can be open, but it's all black on interface, I can's see anything.
Instead, label images is ok , ITKSnap can visualize it .I don't konw why -_-

I met the same error, do you have any solution?

[neheller]

So just to be clear, you are opening an imaging.nii.gz file as "main image" in ITK Snap and it appears all black? Have you tried adjusting the contrast at Tools -> Image Contrast -> Contrast Adjustment?

I do not find images,could you share them again?
