PLATE_DIMENSIONS =
Note:

  • 96 represents a 96-well plate, arranged in 12 columns and 8 rows.

  • 384 represents a 384-well plate, arranged in 24 columns and 16 rows.

  • 16 represents a 16-well Chromium Chip, which has 8 columns and 2 rows. Although a 16-well Chromium Chip does not have 3:2 ratio to be a standard plate, i.e. it has 4:1 ratio, the methods here still apply. Note that the asset shape is a generic one, Shape4x1, although it has been created for the 16-well Chromium Chip.

  • 8 represents a 8-well Chromium Chip, which has 8 columns and 1 row. Note that the asset shape is a generic one, Shape8x1, although it has been created for the 8-well Chromium Chip.

A hash representing the dimensions of different types of plates. The keys are the total number of wells in the plate, and the values are arrays, where the first element is the number of columns and the second element is the number of rows.

Returns:

  • (Hash{Integer => Array<Integer>}) —

    the dimensions of the plates

Hash.new { |_h, _k| [] }.merge(96 => [12, 8], 384 => [24, 16], 16 => [8, 2], 8 => [8, 1])

Class Method Details

.alternate_position(well_position, size, *dimensions) ⇒ Object

Given the well position described in terms of a direction (vertical or horizontal) this function will map it to the alternate positional representation, i.e. a vertical position will be mapped to a horizontal one. It does this with the divisor and multiplier, which will be reversed for the alternate.

NOTE: I don’t like this, it just makes things clearer than it was! NOTE: I hate the nil returns but external code would take too long to change this time round
