[caret-users] File Import issue

[Donna Dierker]

Hi Niranjan,

I can't replicate the problem without the .img file, too, but I did look 
at just the .hdr, and there were some non-standard things about it 
(e.g., pixdim[0]=-1.0).  I wondered whether this might be a NIFTI volume 
written as .hdr/.img, which Caret doesn't yet support?  If so, try 
writing it as a .nii file, and see if you still have the scaling issue.  
(Note that you can always zoom up on the volume, but this gets tedious 
if you have to open the volume often.)
