File Convention

THI file format

THI file is widely used in EPicker workflow, which is defined as a table to store a list of information. The table in a THI file has the format like following:

[Table Header: ColName1 ColNam2 ....]
v1 v2 ...
...
va vb ...
[End]

Each table consists a header line and a ending line. Each THI file can contain multiple tables.

The header line defines the table name(before colon) and the name of each columus (after colon).

THI files used in EPicker

• THI file of particles Each row corresponds to a particle. The columns are the center coordinates (X, Y) and the confidence value (score of the particle).

  [Particle Coordinates: X Y Value]
  1243 512 0.43
  123 5123 0.39
  [End]
  

• THI file of vesicles Each row corresponds to a vesicle. The columns are the center coordinates (X, Y), the radius of vesicle in pixel and the confidence value (score of the particle).

  [Vesicle Coordinates: X Y Radius Value]
  4313 1523 30 0.32
  3323 4152 60 0.28
  [End]
  

• THI file of fibers Each fiber is represented with a group of points, and identifed by a group ID. The points with the same group ID belong to the same fiber. Each row corresponds to a point on a fiber. The columns are the point coordinate (X, Y), group ID, and the confidence value (score of the particle).

  [Helix Coordinates: X Y Group Value]
  123 456 1 0.54
  156 499 1 0.49
  2231 2210 2 0.47
  2456 1982 2 0.46
  [End]
  

• THI file of image list A list of files can stored in a "File List" table. Each row contains a file.

  [File List: Filename]
  /Data/stack_0001_DW.mrc
  /Data/Stack_0002_DW.mrc
