Can not parse dataset #3

Closed NicolasRannou closed 8 years ago

NicolasRannou commented 8 years ago

Hi, It seems the following dataset is not being parsed properly:

The header looks fine but buffer returned is empty.

Thanks for reporting this. I think you may be using an older version in which nifti.readImage() would not correct the time dimension to 1 if it was 0 in the header. So if it is 0, when it calculates the size of the image, it comes out to 0.

Try using the latest build and let me know if that doesn't fix it.

Another possibility... the slope is 0 in that image. Be sure you aren't multiplying that in or else everything will be 0 as well.

Thanks - trying it and will let you know. Another (smaller) dataset from same people which doesn't work: https://drive.google.com/open?id=0B2-PspfnvPNgS3BrTWU0NHhNRlE FYI papaya couldn't display this image.
