Daverage

daverage is the basic command line option for averaging particles in a data folder using alignment parameters expresed inside a table.

Syntax

The basic syntax of the command is:

 output = daverage('myData','t','myTable.tbl');

where output is an structure recording several items (including of course the density map). If you want to use a linux-like notation, you can produce a left-hand-side output wuth the flag ws (short for workspace), i.e.

daverage myData -t myTable.tbl -ws output

Input

Data folder

The location of the particles can be passed through:

• a data folder
• a DBox folder

Table

A regular Dynamo table, than can be passed as file or numeric matrix.

Output

The output structure has several fields.

• .average_raw:
  without compensation for overweighting of fourier pixels

• .average:
  with compensation for the fourier overweighting

• .fweight:
  map of overrrepresentation of fourier components in the output property .average_raw

• .fmask:
  binary mask denoting available fourier coefficients

• .variance:
  variance map

• .fsc:
  fsc values

• .fsc_labels:
  useful information to annotate fsc plots

• .tags:
  list of tags that did actually contribute to the

                       averaging procedure.

• This is useful to control which is the final

                       result of confronting which data is available,
                       which tags are marked in the table, and also
                       which particles where excluded.

• .nanContributions
  map with the number of particles that contributed

                       a NaN value for each pixel.
