Tell it to initialize the registration based on the header information. To do this add --regheader to the command-line. Once the register.dat exists, do not use --regheader unless you want to overwrite your results.

Thanks Doug,

When I run

tkregister2 --targ structuralimage --mov functionalimage --reg register.dat

I got the following error.

====================== target volume XXXXX.img movable volume XXXXXX.img reg file register.dat LoadVol 1 $Id: tkregister2.c,v 1.22 2003/11/05 21:30:50 greve Exp $ Diagnostic Level -1 regio_read_register(): No such file or directory Could not open register.dat Segmentation fault (core dumped) ==========================

What could have been wrong? Thanks. Nam.
