ConvertStar

Description:

The ConvertStar module converts a motive-list (also abbreviated as motl), as defined in the EM-package of Reiner Hegerl, Martinsried, Germany (Hegerl, R. (1996). The EM Program Package: A Platform for Image Processing in Biological Electron Microscopy, J. Struct. Biol. 116: 30-34) into a STAR file (Hall, S.R. (1991) the STAR file: A new format for electronic data transfer and archiving, J. Chem. Inf. Comput. Sci. 31(2) pp 326-333), as used in Bsoft and jsubtomo, and the other way round.

For the conversion from a STAR file to a motive-list, the STAR file has to contain at least the following data items:

data_
_{file extension}.3D_reconstruction.id {id}
_{file extension}.3D_reconstruction.file_name {filename}
_{file extension}.3D_reconstruction_select 1
_{file extension}.3D_reconstruction_voxel_size {voxel sixe}
loop_
_particle.id
_particle.group_id
_particle.magnification
_particle.x
_particle.y
_particle.z
_particle.origin_x
_particle.origin_y
_particle.origin_z
_particle.view_x
_particle.view_y
_particle.view_z
_particle.view_angle
_particle.fom
_particle.select
{List of particle data}

As defined in Hall, S.R. (1991) the STAR file: A new format for electronic data transfer and archiving, J. Chem. Inf. Comput. Sci. 31(2) pp 326-333, a STAR file can contain one or more data blocks (a data block starts with "data_" and has to contain at least the data items from above). If a STAR file contains more than one data block, the ConvertStar module creates a motive-list for every data block, otherwise only one motive-list will be created. The motive-lists will be saved as {starfilename}_{reconstruction filename}.em

If a motive-list (e.g. motivelist.em) is converted into a STAR file, the resulting STAR-file will be saved as {filename_of_motivelist}.star (e.g. motivelist.star).

Ports:

Filename

This file chooser defines the path and the filename of an existing motive-list or STAR file to convert.
