Table column convention

col 1: tag

Identifies the particle number.

col 2: align

0 or 1 Used when a table is fed into Dynamoas initial table for an alignment project. Value 1 tells Dynamo that the particle is to be used during an alignment project, values 0 skips the particle. {T|hola}

col 13: ftype (type of fourier sampling)

Describes the fraction of the Fourier space covered by the particle. Basically it represents the imaging geometry. 0 or 'full' 1 or 'single' beam along z, tilt around y 2 or 'singlex' beam along z, tilt around x 3 or 'cone', beam along z 4 or 'double', 'dual' beam along z, tilts around y and x 5 or 'custom' 6 or 'tilt_z_beam_y' beam along y, tilt around z 7 or 'tilt_x_beam_y' beam along y, tilt around x

For total characterization of the Fourier components covered by the particle, the information in this column needs to be complemented with other columns [14 to 19] depending on the ftype.

cols 24-26: position in tomogram

Given in pixels.

col 34: reference

This column is written by Dynamo during the computation of a multireference alignment project. It marks the reference channel that yielded the highest score for the particle. A "reference" can be seen as a "class" produced by multireference alignment and classification.

col 35: subreference

This column is typically written by Dynamo while creating averages of the particles assigned to different clusters computed through PCA+Kmeans or Hierarchical Ascending Clustering. Thus, in Dynamo jargon, "subreference" can be seen as a "class" produced by classification through PCA+ Kmeans or HAC. The name "subreference" comes from the fact that we frequently use PCA analysis on top of the results attained by Multireference Analysis.
