AMS multiprocess overwrite

[PierreLaville]

When running a second time multiprocess_ams.py on a folder with the same [run_name]:

The '[run_name]' directory already exists and contains an AMS directory with the same run parameters. Do you wish to overwrite ? [y/N] The '[run_name] directory already exists and contains an AMS directory with the same run parameters. Do you wish to overwrite ? [y/N] The '[run_name]' directory already exists and contains an AMS directory with the same run parameters. Do you wish to overwrite ? [y/N]

Consequences:

• it actually overwrites only if input files are the same as the previous run
• in the case you want to run it on other input files, it will add the new output without overwriting
  • problem: [y/N] field gets filled before you can answer yes or no and it runs for ever without completing at all

This is really a minor issue but still worth to be at least reported. The easiest fix being of course not choosing the same [run_name] as before.

This is actually not such a minor issue as I expected: this happens also in a single run when the number of pairs is superior to the nb of threads (4 for instance). The 4 first pairs run and then the "Do you wish to overwrite ? [y/N]" appears, get filled with the rest of the pairs output which never can be computed causing the script to get stuck and never end.

ah yes, this is annoying, I would advise we take out this interactive setup and put a mechanism in place for avoiding to overwrite files and run everything as a multiprocess.
