focus can't set gpu for tomoalign using a system with a single gpu

[n1kt0]

Using the below listed options the tomoalign script in tomography mode can't set the variable 'GPU_to_use_local' the error message is 'Undefined variable.'.

How many GPUs to use = "1"
Which GPU to use = "0"
Cycle over GPUs = "No"
Run only one MotionCor2 instance at a time on the system = "Yes"

The only thing which helped is setting 'How many GPUs to use' to '2' and replacing the script with an older one where the only change is:

diff tomo_driftcor_motioncor2.script /opt/focus/scripts/image/tomoalign/tomo_driftcor_motioncor2.script
125a126,129

set GPU_cycle = "y"
##########################################################################
${proc_2dx}/linblock "WARNING: MotionCor2 will always cycle over the GPUs in Tomography mode!"
##########################################################################

Any suggestions for improvement are welcome!

The same happens in this situation with the gautomatch script.
