h1. MSI-Ptolemy API information for developers

h2. Square_Finding node:

The square finding should operate on each gr image tile at its saved mrc dimension.

# Shell script to call and specified in Blobs settings.

# Output json file is a list of square blob founds by the algorithm.  For each item, it requires the following key, value pairs.

h3. area: integer

number of pixels the square opening on the gr tile image.

h3. center: (integer, integer)

The coordinate of the square opening center (col, row) with (0,0) at the start of the data block in the mrc image.

h3. score: (float)

The score of the blob as goodness of the blob as a good square. The higher the number the better.

h3. vertices: [(integer, integer), (integer, integer), (integer, integer), .....]

convex-hull vertices used by leginon to determine if a cursor position is within the square blob. Same coordinate system as centers.
