NAME
joinwarp2model - Make starting model for refining tomogram join from
initial warping
SYNOPSIS
joinwarp2model options warping_xf_file model_file
DESCRIPTION
Joinwarp2model produces a model file that can be used as a starting
point for a refining model when joining serial tomograms where warping
has been applied in the first alignment stage of joining. Each warping
control point introduced in Midas is converted to a contour with a
pair of points. These two points will display just below and just
above the junction in the joined file that a refining model is being
built on, as required by Xfjointomo. The premise here is that you
have already identified each such pair of points as corresponding
between the two sections when you imposed the warping. It is thus
appropriate and important to keep all of these correspondences in the
refining model. In the ideal case, if the modeled trajectories are all
perfectly consistent with these correspondences, then the correspon-
dences will be retained and the transform fitting will produce a unit
transformation at the correct gap between sections. More realisti-
cally, the correspondences implied by the trajectories will not agree
perfectly with the correspondences created by warping, and the fitting
will average over all of the data, producing a non-unit linear trans-
formation and shifting the warping points out of correspondence to some
extent.
OPTIONS
Joinwarp2model 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.
-input (-i) OR -InputWarpFile File name
Name of input transform file with warping control points. When
Etomo runs Finishjoin, this is the file "joinroot.xf". If
this option is not entered, the first nonoption argument is used
for this filename. One or the other entry is required.
-output (-ou) OR -OutputModelFile File name
Name of output file for model of warp points. If this option is
not entered, the second nonoption argument is used for this
filename. One or the other entry is required.
-joined (-j) OR -JoinedFile File name
Name of join file being modeled. After "Refine Join" is pressed
in Etomo, this is the file "joinroot_modeled.join". If this
filename is not entered, then the "-size" and "-pixel" options
must be entered.
-xform (-x) OR -AppliedTransformFile File name
Name of file of G transforms applied to make the join file.
When Finishjoin is run without the "-xform" option, this is
the file "joinroot.tomoxg", which is copied to "joinroot.warpxg"
if there is warping. However, when Finishjoin is run with
the "-xform" option to make the refined join, "joinroot.tomoxg"
is the final transform file, not the file needed here. Thus,
use "joinroot.warpxg". This entry is required.
-size (-s) OR -SizeOfJoinInXandY Two integers
Actual size in X and Y of the join file being modeled, in binned
pixels if binning was used. This entry is needed if "-joined"
is not entered.
-pixel (-p) OR -PixelSpacing Floating point
Actual pixel spacing in Angstroms of join file being modeled,
which includes any binning applied to make the file. This entry
is needed if "-joined" is not entered.
-offset (-of) OR -OffsetInXandY Two integers
Offset applied when building the join file, in unbinned pixels
if binning was applied. This entry should be the same as the
"-offset" entry to Finishjoin, which is the negative of the
"Shift" values in the text boxes in Etomo.
-binning (-b) OR -BinningOfJoin Integer
Binning applied when building the join file; this entry is
required if binning was applied.
-chunks (-c) OR -ChunkSizes Multiple integers
Number of slices in each section of the join file. This entry
is required so that the program can put the model points at the
right locations just before and after each junction between sec-
tions.
-help (-h) OR -usage
Print help output
-StandardInput
Read parameter entries from standard input
