alignlog(1)                 General Commands Manual                alignlog(1)



NAME
       alignlog - extract data from tiltalign log file

SYNOPSIS
       alignlog  options  [a | b | log_filename]

DESCRIPTION
       This Python script extracts useful sections from the output of Tiltal-
       ign(1).  One or more options may be entered in any order; if multiple
       options are given, the different sections are printed out in the order
       given.  If no filename is entered, alignlog will attempt to extract
       sections from the file align.log.  If a or b is entered instead of a
       filename after the options, then sections will be printed from
       aligna.log or alignb.log, respectively.

OPTIONS
       Alignlog uses the PIP package for input (see the manual page for
       pip).  Options can be specified either as command line arguments
       (with the -) or one per line in a command file (without the -).
       Options can be abbreviated to unique letters; the currently valid
       abbreviations for short names are shown in parentheses.

       -m     Mappings: print variable mappings

       -e     Errors: print errors and ratio of measured to unknowns.  If
              cross-validation is being done, both the residual errors and the
              errors in predicting the positions of points left out will be
              printed.

       -s     Solution: print the alignment solution for each view

       -l     Local: print the location and size of each local area, the num-
              ber of fiducials on each surface, and the mean residual.

       -c     Coordinates: print the 3-D coordinates of the fiducials

       -r     Residuals: print large residuals

       -a     Angles: print planar fits and recommended change in angles

       -b     Beam tilt: print F values (RMS errors) from beam tilt search

       -w     Robust weighting: print output from robust fitting and weighted
              mean residuals.  If cross-validation is being done, both the
              residual errors and the leave-out errors will be printed.  It
              reports leave-out errors without and with robust fitting and the
              benefit from robust fitting (the difference of the two).  It
              reports both unweighted and weighted errors and benefits; the
              weighted benefit value should be the most valid reflection of
              whether robust fitting helped.

       -p     Project log: print output selected for the project log

       -help (-h) OR -usage
              Print help output

       -StandardInput
              Read parameter entries from standard input


EXAMPLES
       Print solutions and errors from align.log:
           alignlog -s -e

       Print 3-D coordinates and angle recommendations from alignb.log:
           alignlog -c -a b
