Name

recons3d_sirt - calculate 3-D reconstruction from a set of projections

Usage

vol = recons3d_sirt(stack, list_proj, radius [, lambda, maxit, symmetry, tolerance])

Input

stack

name of the stack file containing projection data, projections have to be squares, i.e., nx=ny

list_proj
list of projections to be included in the reconstruction
lambda
relaxation constant, (default - 1.0e-4), it has to be adjusted for each reconstruction
maxit
maximum number of iterations (default = 100, should be sufficient)
symmetry
point-group symmetry to be enforced, each projection will enter the reconstruction in all symmetry-related directions. The possibilities are
tolerance
stopping criterion, the program will terminate when the relative improvement of the structure is less than the tolerance set

Output

vol
the 3-D reconstructed volume
