!xmipp_angular_continuous_assign (v3.0)

Usage

Make a continuous angular assignment This program assigns Euler angles to experimental projections by minimizing the difference between the given experimental image and the central slice of a reference volume in Fourier space. All interpolations are based on a B-spline model of the images and the volume. The translations are also optimized. Since an iterative optimization is performed, it must be initialized with some rough estimate of the angles. The output of xmipp_angular_predict can be used as initialization without any transformation. The method is fully described at http://www.ncbi.nlm.nih.gov/pubmed/15885434

Parameters

$``: Metadata with initial alignment $--mode &lt;modeoverwrite> where <mode> can be:

    • $-o, --output &lt;output_file> $``: Reference volume $--gaussian_Fourier &lt;s0.5> $`--gaussian_Real &lt;s`0.5&gt; $`--zerofreq_weight <s`0.> $`--max_iter &lt;max`60&gt; $`--max_shift <s`-1> $`--max_angular_change <a`-1>

Examples and notes

A typical use is:

xmipp_angular_continuous_assign -i anglesFromDiscreteAssignment.doc --ref reference.vol -o assigned_angles.xmd
