Hi Xinman,

I hope that I can help. If I understand correctly, there were 85 images in the data from the scanner. When you created the test images, there should also be 85 images (test1.dcm, test2.dcm, ..., test85.dcm). The code in your Apr 29 post should create one test image for every image from the scanner, so I don't know why you have 67 images in a folder.

You could create new test images from the original 85 images. You know what the b-values are for those images. Try to change the SequenceName values in the new test images to contain 'ep'. You can compare the SequenceName values in the test images to those in the original images to make sure they have the same b-values.

Or you can use other software to convert your DICOM files to NIfTI format, as Kirk recommended.

Best,
Dave
