Xmipp

xmipp_angular_distance (v3.0)

Usage

Computes the angular distance between two angle files. The angular distance is defined as the average angular distance between the 3 vectors of the coordinate system defined by the Euler angles (taking into account any possible symmetry).

Parameters

--ang1 <Metadata1>
Angular document file 1
--ang2 <Metadata2>
Angular document file 2
--oroot <rootname=>
Output rootname rootname.xmd Angular comparison; rootname_vec_diff_hist.txt Histogram of the differences in vector directions; rootname_shift_diff_hist.txt Histogram of the differences in shifts; rootname_rot_diff_hist.txt (verbose>=2) Histogram of the differences in rot; rootname_tilt_diff_hist.txt (verbose>=2) Histogram of the differences in tilt; rootname_psi_diff_hist.txt (verbose>=2) Histogram of the differences in psi; rootname_X_diff_hist.txt (verbose>=2) Histogram of the differences in shiftX; rootname_Y_diff_hist.txt (verbose>=2) Histogram of the differences in shiftY;
--sym <symmetry=>
Symmetry file if any The definition of the symmetry is described at transform_symmetrize
--check_mirrors
Check if mirrored projections give better results
--object_rotation
Use object rotations rather than projection directions fit (Spider, APMQ)
