joinwarp2model(1) General Commands Manual joinwarp2model(1) 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 AUTHOR David Mastronarde SEE ALSO xfjointomo, midas, finishjoin Email bug reports to mast at colorado dot edu.
