Parameters/Metadata for applications stored in the project

These are metadata parameters associated with a 'Project', like a single particle reconstruction, and may be application specific or global. If an application wishes to make parameters available for other applications to see, it should put them in 'bdb:project' in the local directory and name them as described below. Documentation for application specific parameters not really intended for use by other applications appears here as well. This does NOT document parameters stored in the header of individual images, though we strive to use the same names whereever possible.

These parameters can be found in bdb:project

Parameters starting with 'global.' are those which could be used equally by any application, other applications wishing to publish parameters for use by others should prefix them with 'appname.'

global.apix

float

Default A/pix value for a project

global.microscope_voltage

float

Default microscope voltage in kV for a project

global.microscope_cs

float

global.spr_filt_ptcls_map

Dictionary, key is a string, value is a dictionary

In this dictionary the key is the name of a particle file that should almost certainly also exist in the global.spr_ptcls list. The value, which is a dictionary, contains keys which are descriptive strings such as "phase", and values which are the names of filtered files that exist on disk.

global.spr_ref_free_class_aves

This is the cache associated with e2boxer.py.

Not that by filename_DD it is meant to be a string constructed from the original file name, for instance if the file name was 123458.mrc then filename_DD would be literally "123458_DD".

filename_DD

Python dictionary

Image Database Dictionary

filename_DD.auto_boxer_state_TS

string

stores the reference boxes located in this image that are also being used by the associated Autoboxer instance

This dictionary stores the most recently used parameters associated with 2D refinement in e2workflow.py

These parameters can be found in bdb:raw_data#

The raw_directory is used by e2workflow.py for storing imported micrograph/CCD data. The image file tag (e.g. the file tag of /home/somewhere/something.mrc is "something") may be used to access the image, for example

   1 a = EMData("bdb:raw_data#something",0)
   2 b = EMData()
   3 b.read_image("bdb:raw_data#something",0)

These parameters can be found in bdb:particles#

The short story is e2boxer stores particles in this directory, it uses a naming convention where "_ptcls" is appended to the end of the input image names.

e2ctf stores particles in this directory and appends "_ctf_flip" or "_ctf_wiener", depending whether the output data are phase flipped or Wiener filtered.

The longer story is - The particles directory is used by e2ctf, e2boxer and e2workflow for storing boxed particle data that has optionally been filtered. In general e2boxer will be the first program that stores data here, and it can be done in a number of ways. People can save directly to the particles directory from e2boxer using the 'write box particle images' button (name may be different) and by making sure the output format is 'bdb'. e2boxer can also be used from the command line for writing output (output format is a command line argument). This is precisely what occurs from the context of e2workflow, which spawns output writing processes using e2boxer.

Note that a naming convention is employed by e2boxer - if the input image names is something.mrc or "bdb:raw_data#something" then the output particles will be written using the filename "something_ptcls". You can access these images from Python using any of these approaches:

   1 a = EMData.read_images("bdb:raw_data#something_ptcls",[])
   2 n = EMUtil.get_image_count("bdb:raw_data#something_ptcls")
   3 images = []
   4 for i in range(n):
   5     images.append(EMData("bdb:raw_data#something_ptcls",i))

e2ctf will also store filtered particle images in the this directory, and these will be either phase flipped or Wiener filtered. Note that the Wiener filtered data are also phase flipped. These particles are stored in the database with "_ctf_flip" and "_ctf_wiener" appended to the input file names, respectively.

These parameters can be found in bdb:e2boxercache#

The e2boxercache directory has many dedicated particle stacks in it. The currently existing stacks are listed in this table

exclusion_image

EMData database

A binary exclusion image, in shrunken image coordinates

image_thumb

EMData database

A thumbnail of the image

subsampled_image

EMData database

A subsampled version of the image generated by the Gauss mode - Sparx group please add details

coarse_flat_image

EMData database

A coarsened version of the image that has its background flattened

coarse_sigma_image

EMData database

A specialized image that stores the inverse of the local pixel standard deviation - should probably called inverse_sigma_image - this image is in shrunken image coordinates and is used to normalize the correlation image (Roseman). Note that pixels representing 0 standard deviation are left unchanged

flcf_image

EMData database

Locally normalized correlation image (Roseman, Ultramicroscopy)
