This program performs a 2 way even/odd test to determine the resolution of a reconstruction.
eotest [proc=<min proc>,<maxproc>] [hard=<maxpr>] [ctfc=<res in A>] [ctfcw=<SF file>] [median] [sym=<c2,c4,etc>] [mask=<rad>] [pad=<size>] [classkeep=<sigma coef>] [classiter=<iter>] [precen] [imask=<rad>] [xfiles=<a/pix>,<mass in kd>,<ali to>] [amask=<r>,<thr>,<n iter>] [3dit=<n it>] [3dit2=<n it>] [euler2] [fscmp] [refine] [dfilt] [frm2d[=<rad>,<samp>]] [refmaskali] [iter=<n>]
Number of proceesors to use for parallel processing
Hard limit for make3d
[ctfc=<res in A>]
Performs CTF correction filtered to the specified resolution
Performs CTF correction with Wiener filtration using a structure factor specified in a file
Specify this when CTF correction is NOT being performed
Imposes symmetry on the model
Applies an outside mask in several stages of refinement
Pads the model during Fourier reconstruction
Classkeep value for <a href=classalignall.html>classalignall</a>
Iterations for <a href=classalignall.html>classalignall</a>
Indicates that raw particles have been accurately precentered
Applies an inside mask in several stages of refinement
[xfiles=<a/pix>,<mass in kd>,<ali to>]
Used to generate 3d models that are easy to evaluate
This applies an automask between steps in a reconstruction. see automask2 in proc3d. REQUIRES xfiles to be used.
After constructing a model with Fourier reconstruction, this runs several iterations of real-space model 'cleansing'
This is real-space refinement with a special maximum entropy-like feature extraction method
Reassigns Euler angles to class averages using the same step used by refine. ie - 2 will use ang/2 (see <a href=classesrefs.html>classesrefs</a>
Use fsc (frc) to compare images instead of normalized variance
Refine each alignment to subpixel accuracy
Experimental option which will apply a ~matching filter to the projections during class alignment
This will classify using Fast Rotational Matching 2D. rad is the maximum radius of particles; samp is the number of angular sampling points at each radius circle
Select the iteration to do eotest. default to last iteration
This program's options parallel [/eman/eman1/progs/refine.html refine]. 'eotest' options are a subset of refine's options. eotest is used to perform a fairly robust resolution determination on a reconstruction. It is run in the same directory as a completed refine command. Note that the refine command MUST terminate normally. Chances are good that if refine is interrupted in the middle of a run, eotest will not produce valid results. eotest splits each cls file into even and odd halves, then proceeds to build an independent model based on each half of the data. By calculating a Fourier shell correlation between the two resulting maps, a fairly robust resolution determination can be made. For a proper determination, the data should be split into 2, 4, 8, etc sets, then the resolution can be determined by interpolating to the entire data set. The estimate made by comparing 2 halves of the data is actually slightly underestimating the final resolution. Due to the rapid nonlinear falloff in signal to noise ratio at resolution limiting spatial frequencies, this underestimation should be relatively slight in most cases.
