[3dem] Tecnai script

I was thinking on writing a script for a Tecnai F30 that would read a 
text file that store the good spots inside a grid square, move to them, 
and take a defocus pair.
Before writing it, I thought it would be best to ask if someone has 
already written something similar, and if this approach sounds reasonable.
I use lacey carbon, therefore, spotscan, I believe, doesn't fit my needs.
I also found that the focus level doesn't vary so much inside each grid 
square so I do not need to refocus at every step.

The idea is the following, for those familiar with the Technai F30:

   1. Use Stage2 panel to store the good spots inside a grid square (in
      Search mode)
   2. Save the spots in a text file.
   3. Start the script to read the locations.
   4. Move to the first.
   5. Go to Exposure mode.
   6. Take a pair of pictures (different defocus).
   7. Move to the next spot.

Thank you very much
