Foms

[arasskin]

Created a new combined version of the nema7 and jaszczak foms python wrapper and called it foms.py.

The original jaszczak_foms.py and nema7foms.py need to be removed, too.

As discussed, we also want to add an option for plotting 6 separate graphs (one for each sphere) vs. all 6 spheres on a single graph.

On the graphs, we decided to

• use the subset numbers as labels on the x-axis
• draw vertical lines for visual accentuation of subsets

The point of the TODO about adding ability to read foms from generated fom files, was to avoid recalculating the foms if you want to show the plot. As it stands, if I calculate the foms (and the file is written), and then decide I want to look at the graphs, and add the --show-plot=True option, it will calculate all the figures all over again, wasting a lot of time.

So:

• If foms exists in the directory:
  • just read the data from the file, rather than calculating them again
  • print a message at the end, stating that the figures were taken from the cache file, and that the user should delete the file if the figures are to be calculated again (the images might have been regenerated, since the last time)
• If foms is absent:
  • calculate the foms
  • print them out as they are being calculated (as happens already)
  • write the foms file

The lower limit on the y-axis needs to be fixed at zero.

I've rebased this branch on top of the latest master.
