imod2patch(1) imod2patch(1) NAME imod2patch - converts a model to a patch displacement file SYNOPSIS imod2patch <IMOD model file> <new patch file> DESCRIPTION imod2patch converts an IMOD model originally produced by patch2imod back into a list of patch positions and displacements. Specifically, for every contour in the model consisting of at least two points, it outputs a line listing a 3-D position and a displacement. The position is that of the first point. The displacement is the vector from the first to the second point, divided by the scaling factor that was stored as the pixel size in the model header. The resulting file can then be analyzed by findwarp or refinematch. If the original patch file contained correlation coefficients (from corrsearch3d) or residual values (from refinematch or find- warp(1)), and these were stored as values in the model file by patch2imod, then imod2patch will add these values to each line, or a 0 if there is no value for a particular point. In addition, if there outlier fractions output by findwarp and stored in the model, these will be output as well. FILES If the output file already exists, it becomes a backup file with ~ added to its name.
