Error in using the invert-dof

[jinny369]

Hi professors,
I have some problems when typing the command of mirtk help invert-dof in the terminal window.
Some message indicates that /opt/mirtk/lib/tools/invert-dof: error using while loading shared libraries: libMIRTKImage.so.0.
However, I have checked and found the libMIRTKImage.so.0 in the lib file of /opt/mirtk/.
The other commands like register and transform-image, run OK.
Please help to resove this probelm.
Thanks so much for your times.

Are you executing commands using the mirtk entry point, i.e., mirtk invert-dof?
