Error using projection_subtraction.py

[Joe-Cockburn]

Hello,
When I try to run projection_subtraction.py I get the error below. I'm running this on Linux with x86_64 architecture. Do you know what's causing this and how I can solve the issue?
Thanks!
Joe

$ projection_subtraction.py --submap run_class001_SHIFTED.mrc --submask ../shifted_particles/protomer_0_0_0_SHIFTED_INVERTED.mrc --threads 16 ../../Extract/job414/particles.star subtracted_particles.star

NameError: name 'Queue' is not defined. Did you mean: 'queue'?

Ah, I cleverly made the program import the queue object from different sources to account for changes in Python, but then never used the alternate name.

At line 25-28 of projection_subtraction.py, there is a test to import the old name and the new lower case one. If you make it read:

try:
    import Queue
except ImportError:
    import queue
    Queue = queue

Does it work? I won't have time to look deeper and test/fix for real until next week.
