imod2patch(1) General Commands Manual imod2patch(1) NAME imod2patch - converts a model to a patch displacement file SYNOPSIS imod2patch [-v column] IMOD_model_file output_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 extra value columns, such as cor- relation coefficients (from Corrsearch3d) or residual values (from Refinematch or Findwarp), 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. Multi- ple columns of data will be restored and their ID numbers, if present on the first line in the original patch file, will be output to the first line of the new file. If a particular column was made primary with the -v option to Patch2imod, then it can be moved back to its original position with the -v option here. For example, the second column can be made the first general value by entering "-v -2" to Patch2imod, and restored to this position by entering "-v 2" to this program. FILES If the output file already exists, it becomes a backup file with ~ added to its name.
