主旨：Re: the bug about the display of weighted images
收件者："Christophe Phillips" <[log in to unmask]>
Dear Chris:
Thank you for your kind reply.
The image can not be open in spm due to that it can not be resample. Whole
image is white square. There is no program to open the image concurrently.
Can you suggest how to fix this bug?
Thank you.
Dr. Lai
