Stephano, That version of tkregister2 requires the VXL libs. I've posted the binaries for that library for various OSs here: ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/fsdev/nicks For cenots4, the file is called vnl-libso-centos4.tar.gz. Copy it to the directory where you keep tkregister2, change to that directory, and type: tar zxvf vnl-libso-centos4.tar.gz setenv LD_LIBRARY_PATH $PWD Then run tkregister2.

You can actually use the new version of tkregister2 to create an xfm file, tkregister2 --targ targ.mgz --mov mov.img --regheaders --reg reg.dat --xfmout reg.xfm I'm sure you don't have the new version, so I've put it here: ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/tkregister2 This is a 32bit RH linux compile. It may require a few more libraries than you have. Let us know. doug Stefano Pellegrini wrote:Hi everybody, I have a problem with regdat2xfm. I have a reg.dat file that I made using tkregister2 to register a couple of volumes (targ .mgz and mov .img) from one of my subjects. Now, if I try to use the reg.dat file with tkregister2 and the two original files, everything is fine: I ask tkregister2 to read the reg file and the registration is what I made before. Then I convert reg.dat in reg.xfm, and I want to use the .xfm file with mincresample (after having converted the mov .img file in a .mnc file with mri_convert), I get a completely wrong transformation. also, I was wondering if there is anyway to write the output transformed volume directly inside tkregister2. these are the commands I am using data: targ.mgz mov.img (the file I want to move onto targ.mgz) commands: tkregister2 --targ targ.mgz --mov mov.img --regheaders --reg reg.dat regdat2xfm WM.img targ.mgz reg.dat reg.xfm mri_convert targ.mgz targ.mnc mri_convert WM.img WM.mnc mincresample -transformation reg.xfm -like targ.mnc WM.mnc reg_WM.mnc thanks, -stefano _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer_______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
