Thanks Douglas, tkregisterfv looks like a nice alternative. However it only allows .lta format registration files, while all the registration files we previously used are in .reg format. I wonder if there is any way to convert between the two?

 

Many thanks,

Yuelin

Try using tkregisterfv (this is a front end for freeview)

Dear FreeSurfer,

 

Hi, I’m Yuelin, a graduate student from Caltech. I came across an issue using the Tkregister2 registration GUI: the target scan are always rendered with much lower resolution than the movable scan. This difference in resolution makes it almost impossible to registering details. I wonder if this is a known issue and is there any way to solve that? Any information will be very helpful!

 

Our lab currently uses version “freesurfer-local-build-dev-20200114” (this is what’s shown with the “recon-all version” command, but should be 7.0 or 7.1), I also checked some older versions we used before and the same issue exists.

 

Thanks,

Yuelin
