helixhunterP

This program is used to locate possible helices in intermediate resolution maps. Parallelized.

helixhunterP <input> <output> <a/pix> [cyl] [int=<file>] [da=<angle>] [keep=<sigmamult>] [filt=<res>] [proc=<n>]

Parameters:


<input>Input 3D map at 5-8A resolution
<output>Output 3d map of helix positions
<a/pix>Angstroms/pixel in 3D map. Must be <2.
[cyl]Also outputs a 3d map containing the cylinder used in the search.
[int=<file>]Outputs the raw correlation files describing helix locations.
[da=<angle>]Angular step used in the hunt.
[keep=<sigmamult>]Specifies the peak strength that defines a helix.
[filt=<res>]Prefilter resolution in angstroms.
[proc=<n>]Number of processors to use.

Usage:

helixhunterP input.mrc output.mrc 1.5 proc=4

Description

This is a parallelized version of helixhunter. It is currently parallelized using pthreads, and will run only on shared memory machines.

This is superseded by helixhunter2
