Hi Rujing Zha,

It looks like a simple offset error in the data, which should be fixable. Without knowing exactly where the data came from (which format, which file conversions), it’s difficult to say at what stage of processing it occurred. If you have the option, I would first try to re-export the image from the scanner itself. If that doesn’t help, you could see if the slice itself is spatially shifted, i.e. if you look at only this slice it still looks like a proper brain slice, or if it looks like bytes were shifted and the slice itself looks like a collection of shifted rows or columns. In both cases you could then try to manually shift the whole slice or bytes. The last option would be to interpolate that slice from the two slices surrounding it. Apart from the first option (re-export), you would have to get into and manipulate the file-level representation of the image. Depending on your skill set, this might be somewhat daunting, but can also be a very valuable learning experience.

Good luck,
Andreas
