usage: prog [options] This program will take a set of reference-free class-averages (or other projections) and generate a set of possible 3-D initial models. Unlike e2initialmodel.py this program relies on particles having high symmetry, and uses this to generate a more direct solution. It is typically used with icosahedral symmetry, but could also work with other high symmetries. WARNING: this program should not be used with high resolution data without downsampling. If you do it will take an incredibly long time, and not really produce any better results. In most cases, class-averages generated from _lp20 or _lp14 particles would be appropriate. Also, normally you would only use 3-10 class-averages with this program.
| Option | Type | Description |
|---|---|---|
| --version | None | show program's version number and exit |
| --input | str | This file should contain good class-averages to use in constructing the initial model |
| --shrink | int | Optionally shrink the input particles by an integer factor prior to reconstruction. Default=0, no shrinking |
| --sym | None | Specify symmetry - choices are: c<n>, d<n>, h<n>, tet, oct, icos |
| --orientgen | str | The type of orientation generator. Default is eman:delta=3.0:inc_mirror=0. See e2help.py orientgens |
| --verbose, -v | int | verbose level [0-9], higher number means higher level of verboseness |
| --threads | int | Number of threads to run in parallel on a single computer when multi-computer parallelism isn't useful |
| --ppid | int | Set the PID of the parent process, used for cross platform PPID |
