posts/Hooke-update-2.mdwn

   1 In [[an earlier post|Hooke-update]], I reported seeing `surface
   2 distance (m) (m)` columns in my playlist files, but had been unable to
   3 reproduce them.  Today, after [fixing bugs with Curve
   4 copying](http://www.physics.drexel.edu/~wking/code/hg/hgwebdir.cgi/hooke/rev/59390d466f0d),
   5 I did reproduce them with:
   6
   7     $ ./bin/hk.py
   8         -c 'load_playlist test/data/vclamp_picoforce/playlist'
   9         -c 'start_command_capture'
  10         -c 'zero_surface_contact_point --block approach'
  11         -c 'zero_surface_contact_point --block retract'
  12         -c 'stop_command_capture'
  13         -c 'apply_command_stack_to_playlist --enable-evaluate'
  14         -c 'flat_filter_playlist --block retract --min_points 1'
  15     Success
  16     ...
  17     Failure
  18     Expected a list of Peaks, not <class 'hooke.command.Failure'>:
  19       surface distance (m) not in retract (['z piezo (m)', 'deflection (m)',
  20       'surface distance (m) (m)', 'surface deflection (m) (m)']):
  21       list.index(x): x not in list
  22
  23 It appears to be a problem with curve reloading, since it doesn't come
  24 up when I use a playlist with less than 100 (`Playlist._max_loaded`)
  25 curves.
  26
  27 I'll update this post once I've tracked down the culprit.

  29 Update:
  30 [fixed](http://www.physics.drexel.edu/~wking/code/hg/hgwebdir.cgi/hooke/rev/230d4483c9da).
